How do you find perfect square number?

To find a perfect square number, you can check if a number can be expressed as the square of an integer. For example, take the square root of the number; if the result is an integer (e.g., √16 = 4), then the number is a perfect square. Alternatively, you can create perfect squares by squaring whole numbers, such as 1² = 1, 2² = 4, or 3² = 9.
