⁸ Exponent Calculator
Enter a base and an exponent to calculate the power — for example 2¹⁰, 5⁻², or 27^(1/3).

How the Exponent Calculator works
A positive whole exponent multiplies the base by itself. A negative exponent gives the reciprocal, and a fractional exponent is a root.
bⁿ = b × b × … × b (n times)
b⁻ⁿ = 1 ÷ bⁿ
b^(1/n) = ⁿ√b
Step-by-step calculation
- 1Enter the base.
- 2Enter the exponent.
- 3Raise the base to the power.
Worked example
2¹⁰ = 1,024. 5⁻² = 1/25 = 0.04. 27^(1/3) = 3.

Frequently asked questions
What is anything to the power of 0?
Any non-zero number to the power 0 is 1.
Why can I not raise a negative number to 0.5?
That would be the square root of a negative number, which is not a real number.
