Quick answer

An exponent tells you how many times to multiply the base by itself; a negative exponent means the reciprocal, and a fractional one means a root.

The formula

a^(m/n) = ⁿ√(a^m)

Frequently asked questions

What does a fractional exponent mean?

The denominator is a root: 8^(2/3) is the cube root of 8 squared, which equals 4.

Why is anything to the power 0 equal to 1?

Because a^m ÷ a^m = a^(m−m) = a^0, and any nonzero number divided by itself is 1.
