False. 22 = 4
False. 22 = 4
nope! take the square root of 5, 2.236067978... which is not a whole number! hope this helps!
a positive integer
Yes, if it is a whole number but not if it is a fraction
A perfect square is a rational number equal to the square of a whole number.

Yes...because a whole number does not have an irrational part to it.
a positive integer
Yes, if it is a whole number but not if it is a fraction
No. More frequently it is not.
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, it may be not even a rational number. Square root of 2 is 1,414213562... for example.

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.
Yes. The square of an integer is just the number times itself. For any two whole numbers that are multiplied, the answer is always an integer (i.e. no decimals).
