Exponent Calculator
Enter a base and an exponent to compute the base raised to that power. Exponentiation means multiplying the base by itself as many times as the exponent says, so two to the tenth is two multiplied ten times over, which equals one thousand twenty four. This calculator supports negative exponents, which give reciprocals, and fractional exponents, which act as roots, so you can use it for everything from compound growth to geometry. When the base and exponent are whole numbers and the result fits, it uses exact BigInt math so large powers stay precise; otherwise it falls back to a high-precision decimal. Type your two numbers and the answer appears instantly. All of the computation happens locally in your browser, so there is nothing to upload and no server involved.
How to use Exponent Calculator
- Enter the base number.
- Enter the exponent, which may be negative or fractional.
- Read the exact or precise decimal result.
Frequently asked questions
What does raising to a power mean?
It multiplies the base by itself as many times as the exponent, so 2 to the power 3 is 2 times 2 times 2, which is 8.
Can I use negative or fractional exponents?
Yes. A negative exponent gives a reciprocal and a fractional exponent gives a root, such as 9 to the power 0.5 equals 3.
What does a base to the power 0 give?
Any non-zero base raised to the power 0 equals 1.
