Raise a Fraction to a Real Power

Interpret numerator / denominator as a positive rational number, then raise it to power. This task returns a real number rather than an exact fraction; it covers the real-exponent part of the Rational Numbers reference.

Implement rational_to_real_power(numerator, denominator, power).

Input

numerator: The positive numerator.

denominator: The positive denominator.

power: The real-valued exponent.

Output

Return (numerator / denominator) raised to power.

제약 조건

1 ≤ numerator, denominator ≤ 100. −6 ≤ power ≤ 6, with at most two decimal places. Answers are accepted within absolute or relative error 0.000001.
