How to use Exponent Calculator

- Read the result in normal and scientific notation.
About this tool
An exponent tells you how many times to multiply the base by itself, so 2 to the power of 10 is 1,024. Negative exponents give reciprocals (2^-3 = 0.125), and fractional exponents are roots (9^0.5 = 3).
For whole-number bases and small positive exponents the calculator uses big-integer arithmetic, so large answers are exact rather than rounded.
