What are the 5 square numbers?

The first five square numbers are 1, 4, 9, 16, and 25. These numbers are obtained by squaring the integers 1 through 5, respectively. Specifically, they are calculated as follows: (1^2 = 1), (2^2 = 4), (3^2 = 9), (4^2 = 16), and (5^2 = 25). Square numbers represent the area of a square with side lengths equal to whole numbers.
