The term "X²" refers to the mathematical operation of squaring a number, where a number X is multiplied by itself. For example, if X is 3, then X² equals 3 × 3, which is 9. This operation is commonly used in various fields, including algebra, geometry, and statistics, to represent areas, relationships, and growth patterns. In geometry, squaring is often associated with calculating the area of a square, where the length of each side is X. The area is found by squaring the side length, thus reinforcing the connection between the concept of squaring and the properties of geometric shapes.
