Power Calculator

This calculator raises a base to any exponent: 2 to the power of 10 is 1,024, and 5 squared is 25. It also handles negative exponents (2^−3 = 0.125) and fractional ones (9^0.5 = 3, the square root).

Exponents power much of real-world math: compound interest grows exponentially, computer storage doubles in powers of two, and scientific notation uses powers of ten. Try the compound interest calculator to see exponential growth applied to savings.
