2061 is not a perfect square because a perfect square is any number that can be expressed as the square of an integer. You can tell whether a number is a perfect square by taking the square root of the number, which, in this case, would be 45.
25. Since 45. 25 is not an integer, 2061 cannot be a perfect square.

Is 30 a perfect square Yes or no?
No, 30 is not a perfect square. A perfect square is a number that can be expressed as the product of two equal integers. For instance, 4 is a perfect square because it can be written as 2 x 2. 30 cannot be written as the product of two equal integers, so it is not a perfect square.
Why can’t you square a negative number?
Squaring a number means to multiply a number by itself. In mathematics, this means multiplying two of the same numbers together. For example, when you square a number 4, it would be 4 x 4 = 16. However, this only works with positive numbers.
Negative numbers are not able to be squared because the product of two negative numbers is a positive number. When you multiple two negative numbers, the answer will always be a positive number. So when you try to square a negative number, the answer will be a positive number.
For example, if we try to square the number -4, -4 x -4 = 16. This means that the answer is a positive number, even though the number that you have squared is negative. Therefore, you can’t square a negative number.
What is a perfect square factor of 26?
A perfect square factor of 26 is 4. A perfect square is an integer that can be written in the form a^2 for some integer a. As 26 can be written as 4^2, 4 is the perfect square factor of 26. This can also be seen by factorizing 26 as 2 * 13; both 2 and 13 are prime numbers meaning they do not have perfect square factors.
