    The English SERP splits this intent between fraction exponent calculator, fractional exponent calculator, and power of a fraction calculator. The useful result is an exact fraction when the power is integer or the root is exact, otherwise an approximate decimal.

    For an integer exponent, raise the numerator and denominator separately.

    A negative exponent means take the reciprocal before applying the positive power.

    A fractional exponent means raise to the numerator power and take the denominator root.
