# Exponent Calculator

Calculate xⁿ for any base and exponent including negative and fractional values. Shows scientific notation and EU vs US format. Free exponent calculator.

## Quick answer

xⁿ means x multiplied by itself n times. Key rules: x⁻ⁿ = 1/xⁿ (negative exp = reciprocal)  ·  x^(1/n) = ⁿ√x (fractional exp = root)  ·  x⁰ = 1 (any non-zero base to the 0).

## Frequently Asked Questions

x⁻ⁿ = 1/xⁿ. Example: 10⁻³ = 1/1000 = 0.001. Negative exponents appear extensively in science: nanometres (10⁻⁹ m), micrograms (10⁻⁶ g), milliseconds (10⁻³ s).
x^(1/n) = ⁿ√x. So x^(1/2) = √x, x^(1/3) = ∛x. For x^(m/n): take the nth root then raise to the m power. Example: 8^(2/3) = (∛8)² = 2² = 4.
