Question

Is 10 a perfect square? Explain why or why not.

Answer 1

we know that

We say that a number is a perfect square if the square root of that number results in an whole number.

so

$\sqrt{10} = 3.16$

$3.16$ is not a whole number

therefore

the answer is

The number $10$ is not a perfect square

Answer 2

No, 10 is not a perfect square because in order for a number to be a perfect square, you have to see if the numbers that are multiplied to get it are the same. for 10 it isn't a perfect square because the numbers that multiply to get it (1, 2, 5 and 10) are different numbers.
