No, 11250 is not a perfect square.
To determine if a number is a perfect square, we need to determine if a whole number can be squared to equal that number. We can start by taking the square root of 11250, which is √11250 ≈ 106.07. This tells us that there is no whole number that can be squared to equal 11250 since 106 squared is already too small (106^2 = 11,236) and 107 squared is too large (107^2 = 11,449).
Therefore, we can conclude that 11250 is not a perfect square.

What is the square of 11250?
To find the square of 11250, we need to multiply 11250 by itself.
Using the traditional multiplication method, we would start by multiplying the last digit of 11250 (0) by itself, which gives us 0. We then carry the 0 over to the second to last digit, and multiply it by itself and add the carry over. So, we have 5×0 + 0 = 0. We continue this process until we have multiplied all the digits:
11250
x 11250
——–
000000
25000
225000
1125000
——–
126562500
Therefore, the square of 11250 is 126562500.
Alternatively, we could use the exponentiation notation to find the square of 11250. This would involve writing 11250 raised to the power of 2, which is written as 11250^2.
To simplify this calculation, we can use the property that (a x b)^2 = a^2 x b^2. Then, we have:
11250^2 = (100 x 112.5)^2
= 100^2 x (112.5)^2
= 10000 x 12656.25
= 126562500
Again, we arrive at the same answer: the square of 11250 is 126562500.
What is the simplest radical form sqrt 112 112?
To simplify a radical, we must find its perfect square factors.
The prime factorization of 112 is:
112 = 2 * 2 * 2 * 2 * 7
Now, we group the prime factors that appear twice:
112 = 2 * 2 * 2 * 2 * 7
= (2 * 2) * (2 * 2) * 7
= 4 * 4 * 7
Thus, sqrt(112) = sqrt(4 * 4 * 7) = sqrt(4) * sqrt(4) * sqrt(7)
= 2 * 2 * sqrt(7)
= 4 * sqrt(7)
Therefore, the simplest radical form of sqrt(112) is 4sqrt(7).
How to find square root?
Finding the square root of a number is a process of finding a number, which when multiplied by itself, results in the given number. It is denoted using the symbol ‘√’. A perfect square root would be a whole number while an imperfect square root would be a decimal.
One of the basic and popular methods of finding a square root is the Prime Factorization Method. In this method, we list the factors of the number and group them in pairs. Then we multiply the factors in each pair, until two factors are left after all the groups are multiplied. The product of those two factors will give the square root of the number.
Another method to find the square root is the Long Division Method. In this method, we start by grouping the digits in pairs, starting from the right-most of the number. We then find a divisor, such that, when the divisor is multiplied by itself, the result is less than or equal to the grouped digits.
We then subtract the product from the grouped digits, bring down the next pair of digits and continue the same process until all the digits are exhausted. The quotient of the division is the square root of the number.
The most popular method of finding the square root is by using the Radicals Method. In this method, we first express the number under the square root as a product of its prime factors. We then separate each pair of prime factors as a separate entity under the square root symbol. After that, we simplify the radicals by taking out any perfect squares from inside the square root, so that only the square roots of imperfect squares remain.
Lastly, the radical sign is removed and the remaining terms are multiplied.
Square roots can also be found using calculators, which have a square root button. All we have to do is enter the number and press the square root button to get the square root value in decimal form. There are also many online square root calculators available to help with this task.
Finding the square root of a number can be done in several ways including the prime factorization method, long division method, radical method, and the use of calculators. Each method offers a unique way of solving the problem and helps to develop critical thinking and problem-solving skills.
Which of the following are factors of 112 112?
In order to determine which of the following are factors of 112, we need to understand what factors are. Factors are numbers that divide evenly into a larger number without leaving a remainder. The larger number, in this case, is 112.
To find the factors of 112, we can start by dividing it by the smallest prime number, which is 2. We can continue dividing by 2 until we can no longer divide evenly. The result of each division gives us a new factor.
Let’s start:
– 112 ÷ 2 = 56
– 56 ÷ 2 = 28
– 28 ÷ 2 = 14
– 14 ÷ 2 = 7
Since 7 is a prime number, we cannot divide it further. Therefore, the factors of 112 are:
1, 2, 4, 7, 8, 14, 16, 28, 56, and 112.
To check whether a number is a factor of 112, we can divide 112 by that number and see if the result is an integer or a whole number. For example:
– 112 ÷ 8 = 14
– 112 ÷ 13 = 8.6 (not a whole number)
Therefore, 8 is a factor of 112, but 13 is not.
The factors of 112 are 1, 2, 4, 7, 8, 14, 16, 28, 56, and 112.
What number is 841 divisible by?
To find out what number 841 is divisible by, we need to examine its factors. A factor is a number that divides evenly into another number.
Let’s begin by finding the prime factorization of 841:
– 841 is an odd number, and it ends in 1, which means it is not divisible by 2 or 5.
– Dividing 841 by 3 gives us 280 with a remainder of 1. So, 3 is not a factor of 841.
– We can continue by testing odd numbers until we reach the square root of 841, which is 29. Finding factors beyond this point would only result in pairs of factors that we’ve already found. So, we only need to test up to 29.
– Testing 7 gives us a quotient of 120 and a remainder of 1. So, 7 is not a factor of 841.
– Testing 11 gives us a quotient of 76 and a remainder of 5. So, 11 is not a factor of 841.
– Testing 13 gives us a quotient of 64 and a remainder of 9. So, 13 is not a factor of 841.
– Testing 17 gives us a quotient of 49 and no remainder. So, 17 is a factor of 841.
– We can stop here since 17 is a factor of 841. If we continued testing, we’d find that 19, 23, and 29 are not factors of 841.
So, the only factor of 841 is 17. Therefore, 841 is only divisible by 1, 17, and itself (841).
How do you write 841 in Word?

What are all perfect numbers from 1 to 1000?
A perfect number is a positive integer that is equal to the sum of its proper divisors. Proper divisors are positive integers that divide the number evenly, excluding the number itself. The first few perfect numbers are 6, 28, 496, and 8128.
To find all perfect numbers from 1 to 1000, we need to check each integer in that range to see if it is a perfect number. Let’s start by checking the first few integers:
– 1: No proper divisors, so it is not a perfect number.
– 2: No proper divisors, so it is not a perfect number.
– 3: No proper divisors, so it is not a perfect number.
– 4: Proper divisors are 1 and 2, which sum to 3. Therefore, it is not a perfect number.
– 5: No proper divisors, so it is not a perfect number.
– 6: Proper divisors are 1, 2, and 3, which sum to 6. Therefore, it is a perfect number.
– 7: No proper divisors, so it is not a perfect number.
– 8: Proper divisors are 1, 2, and 4, which sum to 7. Therefore, it is not a perfect number.
– 9: Proper divisors are 1 and 3, which sum to 4. Therefore, it is not a perfect number.
– 10: Proper divisors are 1, 2, and 5, which sum to 8. Therefore, it is not a perfect number.
We can continue this process for each integer up to 1000. However, there is a much more efficient way to find all perfect numbers up to a certain limit. It is known that all even perfect numbers can be expressed in the form 2^(p-1) * (2^p – 1), where p is a prime number and (2^p – 1) is also a prime number.
This is known as the Euclid-Euler theorem.
Using this theorem, we only need to check prime numbers p up to a certain limit to find all even perfect numbers. Let’s try this method to find all perfect numbers up to 1000:
– p = 2: (2^(p-1))(2^p – 1) = (2^1)(2^2 – 1) = 6, which is a perfect number.
– p = 3: (2^(p-1))(2^p – 1) = (2^2)(2^3 – 1) = 28, which is a perfect number.
– p = 5: (2^(p-1))(2^p – 1) = (2^4)(2^5 – 1) = 496, which is a perfect number.
– p = 7: (2^(p-1))(2^p – 1) = (2^6)(2^7 – 1) = 8128, which is a perfect number.
– p = 11: (2^(p-1))(2^p – 1) = (2^10)(2^11 – 1) = 33550336, which is a perfect number.
– p = 13: (2^(p-1))(2^p – 1) = (2^12)(2^13 – 1) = 8589869056, which is not less than 1000.
Therefore, the only perfect numbers from 1 to 1000 are 6, 28, 496, and 8128.
What are the first 10 perfect numbers?

How do you check a number is perfect or not?
To check if a number is perfect or not, one can follow a few steps:
1. Find the factors of the given number: A perfect number is one whose sum of factors (excluding the number itself) is equal to the number. For example, if we want to check if the number 6 is perfect or not, we need to find its factors: 1, 2, and 3.
2. Add the factors: Once we have found the factors of the number, we can add them up. For the number 6, the factors are 1, 2, and 3. Their sum is 1+2+3=6.
3. Check the sum: If the sum of the factors is equal to the number itself, then the number is perfect. In the case of 6, the sum of its factors is 6, which is equal to the number itself. Therefore, 6 is a perfect number.
Another way to check whether a number is perfect or not involves using a formula. For an even perfect number, it can be expressed as 2^(p-1) x (2^p-1), where p is a prime number. For example, 6 is a perfect number that can be expressed as 2^(2-1) x (2^2-1) = 2 x 3 x 1 = 6. However, this formula only applies to even perfect numbers, and there are only a few known odd perfect numbers which are yet to be fully discovered by mathematicians.
To check whether a number is perfect or not, we need to find its factors, add them up, and check if the sum is equal to the number itself. Alternatively, for even perfect numbers, we can use the formula 2^(p-1) x (2^p-1) where p is a prime number. Perfect numbers have been known to fascinate mathematicians for centuries, and they continue to be an area of active research and exploration.
