If p and q are prime numbers, how many divisors does the product p^6 * q^7 have?
Choose the correct choice.
A) 40	B) 56	C) 60	D) 62	E) 70
when a number N=a^x*b^y, where a and b are prime numbers, and x, y are positive integers, the number of divisors of N=(x+1)(y+1)   Therefore, the answer is B. 7*8=56
