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.
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.
What do I need to enter into the Exponent Calculator?
Just 2 values: base, exponent. Every field starts with a realistic example, so you can change one number at a time and watch the result update instantly.
How does the Exponent Calculator work out the 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. It applies the formula a^(m/n) = ⁿ√(a^m) and shows the working so you can check each step by hand.
Is the Exponent Calculator free, and do I need an account?
It is completely free with no sign-up, no download and no usage limit. Everything is calculated in your browser, so the numbers you type never leave your device.
