Exponent Calculator

Raise any number to any power. Whole-number powers are computed exactly, even when the answer has thousands of digits.

What is the Exponent Calculator?

An exponent tells you how many times to multiply a number (the base) by itself. Negative exponents mean reciprocals and fractional exponents mean roots.

How does it work?

For whole-number bases and exponents the calculator uses arbitrary-precision integers. Other cases use standard floating-point arithmetic.

Formula

aⁿ = a × a × … × a (n times)
a⁻ⁿ = 1 ÷ aⁿ
a^(1/n) = ⁿ√a

Example

2¹⁰ = 1,024. 10⁻² = 0.01. 16^0.5 = 4.

Frequently asked questions

What is any number to the power 0?
