About the Exponent Calculator

This exponent calculator computes the value of a base raised to any exponent (power). It handles positive exponents, negative exponents (returning 1/base^{|exp|}), zero exponents, and fractional exponents (roots). Results are shown in both decimal and scientific notation for large numbers.

The Formula

bⁿ = b × b × ... × b (n times)   b⁻ⁿ = 1 / bⁿ   b⁰ = 1   b^(1/n) = ⁿ√b

Frequently Asked Questions

What does a negative exponent mean?

A negative exponent means the reciprocal of the base raised to the positive exponent. For example, 2⁻³ = 1 / 2³ = 1/8 = 0.125. The formula is b⁻ⁿ = 1 / bⁿ.

What happens when the exponent is zero?

Any non-zero base raised to the power of zero equals 1. For example, 5⁰ = 1 and 100⁰ = 1. The expression 0⁰ is undefined and will show an error in the calculator.
