If a, p, q, and r are positive integers and (p)×(q)×(r)=a^2, which of the following could be the values of p, q, and r?	Pick:
A) 3, 16, 25
B) 9, 25, 24
C) 2, 25, 32
D) 2, 9, 16
E) 8, 16, 36
This is one of those questions where using the given options is fastest way to get the solution. We need to find a set where 3 numbers can be paired into 2 pairs of some numbers because we need a product which is a square number.   C fits the bill. 2*25*32 = 2*5*5*8*4 = 5*5*8*8   ans 2, 25, 32
