n^2
The notation "n^2" represents a mathematical expression where a number, denoted as n, is multiplied by itself. For example, if n equals 3, then n^2 equals 3 × 3, which is 9. This concept is commonly used in various fields, including algebra and computer science, to describe relationships and growth patterns.
In terms of geometry, n^2 can represent the area of a square with sides of length n. If each side of the square measures n units, the total area will be n^2 square units. This relationship helps in understanding how dimensions affect area in two-dimensional shapes.
