How it works

bⁿ = b × b × … (n times); b⁻ⁿ = 1/bⁿ; b^(1/n) = ⁿ√b

Frequently Asked Questions

What does a negative exponent mean?
The reciprocal: 2⁻³ = 1/2³ = 0.125. Negative exponents never make the result negative — they make it small.
What do fractional exponents mean?
Roots: x^(1/2) is the square root, x^(2/3) is the cube root squared. Any rational exponent combines a power and a root.
What is anything to the power of zero?
1, for every nonzero base — it keeps the rule bᵐ ÷ bⁿ = bᵐ⁻ⁿ consistent. 0⁰ is left undefined or defined as 1 depending on context.
