Numbers with square roots that are whole numbers are called perfect squares. Examples of perfect squares include 0, 1, 4, 9, 16, and so on, as their square roots (0, 1, 2, 3, 4) are also whole numbers. Perfect squares arise from multiplying an integer by itself.
Any number squared except 0 is a perfect square so it follows that prime numbers are less common than perfect squares.
40 is a not perfect square.
