Simple, four.
A perfect square is a rational number equal to the square of a whole number.
Some square roots of whole numbers are integers, some of them are irrational numbers. The square root of four for instance is a rational number, 2. The square root of two however is an irrational number, approximately 1.414211356.
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.

No. to be a perfect square, you have to be able to square root it and get a whole number (NOT a decimal) the square root of 3 is 1.732. (1.7322 = 3) a perfect square is a number like 4 the square root of four is 2 (22 = 4)
One over four 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.
nope! take the square root of 5, 2.236067978... which is not a whole number! hope this helps!
