If both 5^2 and 3^3 are factors of n x (2^5) x (12^2) x (7^3), what is the smallest possible positive value of n?	Select the correct option.
A) 25	B) 75	C) 125	D) 150	E) 175
(2^5) x (12^2) x (7^3) has two appearances of 3 (in 12^2) and no appearances of 5.   Thus n must include at least 3 * 5^2 = 75   The answer is 75.
