Question

What does it mean to say a number is a perfect square

Answer 1

I said u multiply two integers by each other to get this. Am I right

Answer 2

yup

Answer 3

no. it's not just any two integers.

If x is a perfect square, then x = n*n
for some number n.
That is , the two integers must be the same.

To determine if a number is a perfect square, you need to understand the concept of square numbers and their properties.

A perfect square is a number that can be expressed as the product of two identical integers, where both the base and exponent of the number are equal. In other words, it is the result of multiplying an integer by itself.

For example, let's consider the number 9. It can be expressed as 3 * 3, which means 9 is a perfect square because it is formed by multiplying the integer 3 by itself.

To check if a number is a perfect square, you can take the square root of the number. If the square root is an integer, then the number is a perfect square. If the square root is not an integer, then the number is not a perfect square.

For instance, let's determine if 16 is a perfect square. Taking the square root of 16 gives us 4, which is an integer. Therefore, 16 is a perfect square.

On the other hand, let's consider the number 21. Taking the square root of 21 gives us approximately 4.5825, which is not an integer. Hence, 21 is not a perfect square.

In summary, to determine if a number is a perfect square, you need to find its square root. If the square root is an integer, the number is a perfect square; otherwise, it is not.
