Formula
The power repeats the base, or uses the reciprocal when the exponent is negative:
Power = base ^ exponent
A logarithm undoes this. Scientific notation separates a coefficient from a power of ten.
Assumptions
- The exponent is from -20 to 20.
- A negative base uses a whole exponent.
Worked example
2 raised to the 10th power is 1,024.
Input definitions

Questions
What is a negative exponent?
It is the reciprocal of the positive power. 2 raised to -1 is 0.5.
Why is a fractional exponent rejected for a negative base?
That root is not a real number in this calculator.
