The expression "g^n" represents a mathematical notation where "g" is a base and "n" is an exponent. This notation indicates that the base "g" is multiplied by itself "n" times. For example, if g = 2 and n = 3, then g^n equals 2 × 2 × 2, which equals 8. Exponents are a fundamental concept in mathematics, often used in various fields such as algebra, calculus, and computer science. They help simplify expressions and solve equations involving powers. Understanding "g^n" is essential for grasping more complex mathematical ideas and applications.
