No, it does not; it could be a fraction (or, what amounts to the same thing, a repeating decimal), a negative number (in fact every strictly positive number has 2 square roots, one positive, one negative, such as the square roots of 25 are 5 and -5), an irrational number (like the square root of 2), or an imaginary number (like the square root of -49).
The square root of 16 is 4 which is a whole number.
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.
The square root of 26 is not a whole number
A perfect square root is where the square root of a number equals another whole number. For example, the square root of 144 is 12. 12 is a whole number thus 144 is a perfect square root.
Negative the square root of 36 is -6, which is a whole number.
The square root of 55 to the nearest whole number is 7.
nope! take the square root of 5, 2.236067978... which is not a whole number! hope this helps!
If the whole number is a perfect square, its square root is rational. If not, it's not.
48 is not a square number, so the square root of 48 is irrational and can not be represented as a whole number.
if its square root is a whole number
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.
