Both the positive and negative roots of whole numbers, except zero, can be determined. The square root of zero is zero. The value is neither positive nor negative. Zero (a whole number) is a perfect square.

The positive and negative square root of any whole number other than a perfect square lies between two consecutive integers (e.g., √57 lies between 7 and 8 since 7² = 49 and 8² = 64; −√11 lies between −4 and −3 since (−4)² = 16 and (−3)² = 9).

The power of a number represents repeated multiplication of the number (e.g., 8³ = 8 · 8 · 8). The base is the number that is multiplied, and the exponent represents the number of times the base is used as a factor. In the example, 8 is the base, and 3 is the exponent.
