Exponent Calculator

Enter a base and an exponent to calculate the result, including negative and fractional exponents.

How to Use the Exponent Calculator

Base and exponent — two fields; try a negative or fractional exponent to see the calculator handle reciprocals and roots the same way it handles whole-number powers.

base^exponent = base × base × ... (exponent times)

2^4 is 2 × 2 × 2 × 2, which is 16. That's the whole idea — an exponent just counts repeated multiplication. This Exponent Calculator handles the straightforward case and the two that trip people up: negative and fractional exponents.

Negative flips it into a fraction: base^(-n) = 1 ÷ base^n, so 2^(-3) is 1 ÷ 8, or 0.125. Fractional turns it into a root instead — base^(1/n) is the nth root of base, meaning 8^(1/3) asks "what cubed gives 8" and answers 2. Stack a numerator on that fraction (base^(m/n)) and you're taking the nth root, then raising it to the mth power.

Zero as an exponent is oddly clean: any non-zero base to the power of 0 is 1, always, regardless of the base's size. 0^0 itself is genuinely contested territory across different fields — this calculator flags it rather than picking a side.
