For integers x, y, and z, if (3^x) (4^y) (5^z) = 52,428,800,000 and x + y + z = 17, what is the value of xy/z? Choose the correct choice from the following.
A) 0	B) 2	C) 4	D) 6	E) 8
The number 52,428,800,000 is not divisible by 3. (We can verify this by adding the digits of the number to see that the sum is not a multiple of 3.)   Thus x = 0 and xy/z = 0.   The answer is 0.
