Exponent Calculator

What this does

An exponent calculator raises a base to a power, the exponent tells you how many times to multiply the base by itself. It handles whole, negative, fractional, and zero exponents.

How to use it

1. Enter the base.
2. Enter the exponent (power).
3. Read the result.

How it works

A positive whole exponent repeats multiplication. A negative exponent is one over the positive power. A fractional exponent is a root, x^(1/2) is the square root of x. Any non-zero base to the power 0 is 1.

result = base^exponent

Understanding your result

A negative exponent flips the result into a fraction, since base⁻ⁿ equals 1 ÷ baseⁿ, and a fractional exponent is a root rather than a repeated product. Watch the sign of the base: a negative base to an even power is positive, to an odd power is negative, and a negative base with a fractional exponent often has no real value.

Example

2^10 = 1024, 2^-1 = 0.5, and 9^0.5 = 3.
