How to use this calculator
A positive exponent multiplies the base repeatedly for integer exponents. Negative powers take the reciprocal. Solve a missing exponent using logarithms, or find a real base/root from the exponent and result. For positive results and even integer exponents both signed real roots are listed.
- Enter find, base, exponent and review the remaining options.
- Select Calculate or change a value to update the result. Read the result label and units before copying.
- Use Reset to restore the worked starting values.
Formula and method
Some negative-base fractional powers have no real result. Zero to a nonpositive power is rejected.
Worked example
2^10 = 1,024.
Questions about exponent calculator
What does a negative exponent mean?
For a nonzero base, a negative exponent gives a reciprocal: 2^−3 = 1/8 = 0.125. Zero to a nonpositive exponent is rejected. This tool returns finite real results rather than complex numbers.
What assumptions should I check?
Some negative-base fractional powers have no real result. Zero to a nonpositive power is rejected.
