If you cube a prime number (7), then the only number that will go into the new number (343) evenly is the original number (7) and the square of that original (49). That makes 2 positive integer divisors. If you multiply 2 prime numbers (7 and 11), then the new number (77) is only evenly divisible by the 2 prime numbers (7 and 11). That also makes 2 positive integer divisors. 2 = 2. (C).
