Recommendations
Tailored to your live inputs and result—guidance only, not professional advice.
- Check units
Confirm units and mode
Most calculation mistakes come from mixed units or the wrong mode (degrees vs radians, hyp vs leg). Double-check labels before using the number.

How to Calculate Factorial and Exponent Step-by-Step
- 1Enter n for the factorial.
- 2Enter base and exponent for the power.
- 3Review both results.
Governing formula
n! = 1·2·…·n · a^b = exp(b·ln a)
Computes factorial and/or exponentiation for the provided inputs.
Example: set n for Factorial = 6, Exponent Base = 2, Exponent = 8, then read the result.
