Why is the product 8x8 called a square number?

Answer 1

A square number is a number that results from multiplying an integer by itself. In this case, 8 multiplied by 8 equals 64, making it a square number. The name "square" comes from the fact that if you were to draw a square with sides of length 8 units, the area of that square would be 64 square units, hence the term "square number."

Answer 2

A square number, also known as a perfect square, is simply the square of an integer.
