Detailed explanation-1: -Informally: When you multiply an integer (a “whole” number, positive, negative or zero) times itself, the resulting product is called a square number, or a perfect square or simply “a square.” So, 0, 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, and so on, are all square numbers.
Detailed explanation-2: -A number is a perfect square or a square number if its square root is an integer, which means it is an integer’s product with itself.
Detailed explanation-3: -Multiplying a number by itself means squaring the number. The first four square numbers are one, four, nine, and 16. This is because one squared or one multiplied by one is one, two squared is four, three squared is nine, and four squared is 16.
Detailed explanation-4: -Not all even numbers are perfect squares. In fact, many perfect squares are odd numbers. The first ten perfect squares are 1, 4, 9, 16, 25, 36, 49, 64, 81, and 100.
Detailed explanation-5: -So we can say, Yes, the product of two perfect squares is always a perfect square.
