Formula

xⁿ means x multiplied by itself n times

Example

2¹⁰ = 2×2×…×2 (ten times) = 1024.

Negative and fractional exponents

A negative exponent flips the result: 2⁻³ = 1/(2³) = 0.125. A fractional exponent is a root: x^(1/2) is √x and x^(1/3) is the cube root of x.

Key exponent rules

Multiply powers with the same base by adding exponents (x² × x³ = x⁵). Raise a power to another power by multiplying exponents ((x²)³ = x⁶). These rules let you simplify big expressions before computing.

Frequently asked questions

What does anything to the power of zero equal?

One (for every non-zero base): x⁰ = 1.

What is 0 to the power of 0?

Mathematically it is undefined, though most programming languages define it as 1 for convenience.
