Raise a base to a power, including negative exponents and exact fractional exponents such as 1/2 and 1/3. Includes scientific notation and reciprocal output.
What this exponent calculator supports
Search results for exponent calculators expect a fast power tool: enter a base and an exponent, then get the value with scientific notation and edge-case handling.
a is the base and n is the exponent. The exponent can be positive, negative, zero, or an exact fraction.
- Use negative exponents to calculate reciprocals.
- Use 1/2, 1/3, or another exact fraction for rational exponents.
- For a negative base with a fractional exponent, a real result is returned only when the exact denominator is odd.
Power rules used here
A negative exponent means the reciprocal, as long as the base is not zero.
A fractional exponent with numerator 1 is the corresponding root for valid real-number cases.
