A perfect square is a rational number equal to the square of a whole number.
When the whole number is a perfect square, ie it is a whole number squared.
The square root of 15 is not a whole number.
The square of every positive or negative even whole number is a positive even whole number. The square of every positive or negative odd whole number is a positive odd whole number. There are an infinite number of each kind.
nope! take the square root of 5, 2.236067978... which is not a whole number! hope this helps!
A perfect square is a rational number equal to the square of a whole number.
The square root of 16 is 4 which is a whole number.
When the whole number is a perfect square, ie it is a whole number squared.
The most likely answer is "Perfect square".
The square root of 15 is not a whole number.
The whole number closest to the square root of 65 is 8. The whole number closest to the square root of 65 is 8.
if its square root is a whole number
The square of every positive or negative even whole number is a positive even whole number. The square of every positive or negative odd whole number is a positive odd whole number. There are an infinite number of each kind.

Yes. The square of a whole number is always a whole number. For example, 3 squared is 9, so the square root of 9 is 3. What you never have, is the square root of a whole number being a fraction that is not a whole number. The square root of a whole number is either a whole number or an irrational number. For example, the square root of 2 is irrational, because there are no 2 whole numbers a and b such that a/b squared is 2. This is not terribly difficult to prove, but I have already said too much; I have answered your question.

No. The square root of 249 is not a whole number, therefore it is not a square number.
