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, double 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;
}
