How it works

A useful distinction

Repeated growth compounds the multiplier

A 10% increase repeated three times uses 1.1³ = 1.331, so the total increase is 33.1%, not 30%. Enter the growth multiplier as the base and the number of repeated steps as the exponent.

Distinguishing a base from its exponent

The base is the quantity being raised to a power, while the exponent controls the operation. Parentheses matter when the base is negative: a negative base raised to a power is different from negating an already computed power. Check the supported real-number domain for fractional exponents. Very large powers can also exceed the precision or range of the selected numerical method.

Power: formula and assumptions

Result = base ^ exponent.

This real-number tool does not return complex values for fractional powers of negative bases.

Common questions

What does a negative exponent mean?

For a nonzero base, a negative exponent takes the reciprocal of the corresponding positive power; for example, 2^−3 is 1/8.

Will a fractional power of a negative base return a complex value?

No. This mode is restricted to supported real-number results and does not calculate complex powers.
