What is a negative exponent?

A negative exponent means take the reciprocal: b⁻ⁿ = 1/bⁿ. For example, 2⁻³ = 1/8 = 0.125.

What is a fractional exponent?

A fractional exponent represents a root: b^(1/n) = ⁿ√b. So 8^(1/3) = ∛8 = 2. And b^(m/n) = (ⁿ√b)ᵐ.

What is any number to the power of 0?

Any non-zero number raised to the power of 0 equals 1. This is a fundamental rule of exponents: b⁰ = 1 for all b ≠ 0.

Exponent Calculator — Calculate Powers

The Exponent Calculator computes the value of any base number raised to any power (exponent). Also known as a power calculator, it handles positive, negative, and fractional exponents. Exponentiation is fundamental in mathematics, science, finance (compound interest), and computing.
