n²
The expression "n²" represents a mathematical operation known as squaring a number. In this context, "n" is a variable that can represent any real number. When you square a number, you multiply it by itself. For example, if n equals 3, then n² equals 3 × 3, which is 9.
Squaring numbers is a fundamental concept in mathematics and is often used in various fields, including geometry, algebra, and statistics. The result of n² can help calculate areas of squares, analyze data distributions, and solve equations. Understanding this concept is essential for further studies in mathematics.
