Exponent (Power) Calculator
Enter a base number and an exponent to calculate the result of raising the base to that power.
Exponent (Power) Calculator
Calculate the result of raising a base number to an exponent, including fractional and negative exponents.
This is a mathematical calculation. A negative base raised to a fractional exponent may produce an undefined (not-a-number) result, consistent with standard mathematical rules.
Raising a number to a power (exponentiation) means multiplying the base by itself that many times — this calculator handles whole, negative and fractional exponents alike, so it also works for finding roots (a fractional exponent like 0.5 gives a square root).
Example
- With the default values shown above, this calculator returns: Result ≈ 1,024.000000.
Frequently Asked Questions
Can the exponent be negative?
Yes — a negative exponent produces the reciprocal, e.g. 2 to the power of -2 equals 1/4 = 0.25.
Can I use this to find a square root?
Yes — set the exponent to 0.5 to calculate a square root, or 1/3 (about 0.3333) to calculate a cube root.
