If a natural number m can be expressed as n2 (where n is a natural number), then m is the square root or perfect square.

             i.e. if m = n2          (m, n – natural numbers)

             E.g. 81 = 3 × 3 × 3 × 3

                 = 32 × 32 = (3 × 3)2 = 92

             Hence, 9 is the square root of 81.
