About this calculator
An exponent calculator raises a base to a power — repeated multiplication of the base by itself. It handles whole, negative and fractional exponents: a negative exponent gives the reciprocal, and a fractional exponent is a root. Enter the base and exponent to see the result.
Frequently asked questions
What does a negative exponent mean?
A negative exponent is the reciprocal of the positive power. 2⁻³ = 1 ÷ 2³ = 1/8 = 0.125.
What is a fractional exponent?
A fractional exponent is a root: x^(1/2) is the square root of x, and x^(1/3) is the cube root. So 8^(1/3) = 2.
