The method below implements the exponentiation operation recursively by taking advantage of the fact that, if the exponent n is even, then xn = (x n/2)2. Select the expression that should be used to complete the method so that it computes the result correctly. public static double power(double base, int exponent) { if (exponent % 2 != 0) // if exponent is odd { return base * power(base, exponent – 1); } else if (exponent > 0) { double temp = ________________________ ; return temp * temp; } return base; }
