Power Calculator

Use this calculator for powers and roots written as exponents: squares, cubes, compound growth of the form (1 + r)^t, and negative or fractional exponents. The result is Math.pow(base, exponent), the real IEEE power.

Special cases follow IEEE rules: a negative base with a non-integer exponent may yield NaN (not a real number). 0^0 is treated as 1 in JavaScript. Very large results overflow to Infinity.

For a square root of a non-negative number, the dedicated square-root page is simpler. For an nth root with an odd-integer degree of a negative, use the nth-root calculator.

Base: The number being raised (the bottom of a^b).

Exponent: The power (the b in a^b). 2 is a square, 3 a cube, 0.5 a square root.

Result: base raised to the exponent.
