729 is not a perfect cube because it cannot be expressed as the result of an integer raised to the third power. In other words, there is no integer ‘x’ that you can multiply by itself, for three times that will equal 729.
Any number can be expressed as a perfect cube as long a you go far enough in the power range. However, 729 requires a power of 3. 60502 – which is not a whole number and therefore, makes 729 not a perfect cube.

Is 729 a perfect cube give reason in the support of your answer?
Yes, 729 is a perfect cube. This is because 729 can be written as 3^3, which is an expression that indicates 729 is the product of 3 multiplied by itself three times (3x3x3). This expression can also be written as 3 to the power of 3, or ‘cubed’ (3^3).
Because the number is cubed, it can be said to be a perfect cube.
What’s the cube of 729?
The cube of 729 is 5,487,531,441. To calculate the cube of 729, you would multiply 729 by itself three time. So the calculation would look like this:
729 * 729 * 729 = 5,487,531,441
Does 729 have a square root?
Yes, 729 has a square root. The square root of 729 is equal to 27, which is a real number. It is important to note that the square root of any number is always equal to the number itself raised to the power of 1/2.
729 can be expressed in exponential notation as 729 = 73. To calculate the square root of 729, you need to take the principal root of 3, which can be expressed as 3¹∕₂ or 3^(1/2). Therefore, the square root of 729 is equal to 3^(1/2), which is equal to 27.
Which of these numbers is not a cube number * 10000 343 64 729?
The number 343 is not a cube number * 10000. Cube numbers are whole numbers whose cubes are also whole numbers, so the number must be a perfect cube and the cube of the number must be a multiple of 10,000.
A cube number can only be the cube of an integer; 343 is not the cube of any integer and therefore cannot be a cube number multiplied by 10,000. The other numbers, 64 and 729, are both cube numbers, as they are the cubes of 8 and 9, respectively.
8 * 8 * 8 = 512, which is 512 * 20 = 10240, and 9 * 9 * 9 = 729, which is 729 * 20 = 14,580, both of which are multiples of 10,000.
How do you find the cube root of 729?
The cube root of 729 can be found in various ways. The simplest way is to use a calculator to calculate the cube root of 729, which is 9.
Alternatively, you can use the prime factorization method to find the cube root of 729. Since 729 is a perfect cube, it can be expressed as a product of three equal factors, known as a prime factor cube.
In this case, the three factors are 9x9x9, or 729. Therefore, the cube root of 729 is 9.
The last method to find the cube root of 729 is the cube root estimator. This method uses the greatest perfect cube, which is 64, and estimates the cube root of 729, which is 9.
To do this, start by subtracting 729 from 64 until the difference is greater than 0. After subtracting 64 from 729 three times, you will have a difference of 81. Then, add 9 (one of the factors of 729) to the difference to get 90.
Since 90 is greater than 64, the cube root of 729 is 9.
Therefore, the cube root of 729 is 9, by all the three methods.
Is 729 a square and cube number?
Yes, 729 is a square and cube number. A square number is any number that can be expressed as the product of two equal integers, and a cube number is any number that can be expressed as the product of three equal integers.
729 can be expressed as the product of 9 x 9 (a square number) and also as the product of 3 x 3 x 3 (a cube number). Therefore 729 is both a square and cube number.
What is the fastest way to find the cube root?
The fastest way to find the cube root is by using an inverse operation. An inverse operation involves taking the opposite operation (or inverse operation) of the operation used to create the original cube root.
For example, if you wanted to find the cube root of 8, you would perform a cube operation (x^3 = 8) to get 8, and then you would use an inverse operation (x^{1/3} = 8) to get the cube root of 8. This method is not only fast, but it is also accurate.
Additionally, there are many online calculators that are available to calculate cube roots quickly and easily.
How do you calculate a cube?
To calculate the volume of a cube, you will need to use the formula V = s3, where V stands for the volume and s is the side length of the cube. To find the side length of a cube, you will need to use the formula s = √V, where V is the volume of the cube.
To calculate the volume of a cube, start by multiplying the side length, s, of the cube by itself twice. This will give you the volume of the cube: V = s × s × s.
If you need to find the side length of a cube and you have the volume, use the formula s = √V, which should give you the side length.
For example, for a cube with a volume of 900 cm3, you can calculate the side length with the formula:
s = √900 = 30 cm
Therefore, the side length of this cube is 30 cm and its volume is 900 cm3.
