What is negative power?

Negative power refers to exponents that are less than zero, which represent the reciprocal of the base raised to the absolute value of the exponent. For example, ( a^{-n} ) equals ( \frac{1}{a^n} ) for any non-zero base ( a ) and positive integer ( n ). This concept is commonly used in mathematics and science, particularly in calculations involving fractions and inverse relationships. Negative powers help simplify expressions and solve equations effectively.
