Exponent Calculator

Raise a base to any exponent — negative, fractional, or large — with scientific notation for extremes.

Inputs

Base (b)

Exponent (n)

Result

2^10

1,024

How it's calculated

bⁿ, where b⁻ⁿ = 1/bⁿ and b^(1/n) is the nth root of b.

What does a negative exponent mean?

b⁻ⁿ equals 1 divided by bⁿ — for example, 2⁻³ = 1/8 = 0.125.

Can I use a fractional exponent?

Yes. b^(1/2) is the square root of b; b^(1/3) is the cube root, and so on.
