Exponent Calculator

Calculate powers

Enter a base and exponent to calculate a power. The calculator supports positive, negative, and fractional exponents within normal browser numeric limits. Use parentheses when the base is a compound expression.

Exponent rules

A positive integer exponent multiplies the base repeatedly. A zero exponent gives 1 for a non-zero base. A negative exponent gives the reciprocal of the corresponding positive power. Fractional exponents can represent roots when the real result is defined.

Worked example

2 raised to the 10th power equals 1024. For a compound base, enter (3+1)^2 so the intended order is explicit.
