To figure out if a number is a perfect square, one has to see if its square root is a whole number. A perfect square is simply the result of multiplying an integer by itself. For instance, both 4 (which is 2^2) and 9 (which is 3^2) are perfect squares. There are several ways to find out if a number is a perfect square, including prime factorization, testing the digital root, or simply using a square root calculator.
