How Exponents Work

An exponent tells you how many times to multiply the base by itself.

bⁿ = b × b × … × b (n times)   b⁰ = 1   b⁻ⁿ = 1 ÷ bⁿ   b^(1/n) = ⁿ√b
bᵐ × bⁿ = bᵐ⁺ⁿ   (bᵐ)ⁿ = bᵐⁿ   bᵐ ÷ bⁿ = bᵐ⁻ⁿ

Worked Example

Tips

Watch parentheses with negatives: (−2)⁴ = 16, but −2⁴ means −(2⁴) = −16. Enter a negative base here to get the parenthesized version. Fractions work as exponents: type 1/3.
