if x and y are both odd prime numbers and x < y , how many distinct positive integer t factors does 2 xy have ?
since 2 xy prime t factors are x ^ 1 * y ^ 1 * 2 ^ 1 , its total number or factors must be ( 1 + 1 ) ( 1 + 1 ) ( 1 + 1 ) = 2 ^ 3 = 8 . thus , i think d would be the correct answer .
multiply(multiply(2, add(const_1, const_1)), add(const_1, const_1))
