(highest being 47 in verbal with two repeats) I went to the test feeling confident that I'd do well. Before the...

Hi Dana,
Excellent explanation. I was too focused on p, q value and was complicating it.
At the least both ab or cd should come up to 4 to justify a perfect square. I spent abt 10 minutes before i posted it on here.
Source is http://gmat-maths.blocked/
Thanks

easy explanation pls
p^a * q^b * r^c * s^d = x, where x is a perfect square. If p, q, r, and s are prime integers, are they distinct?
(1) 18 is a factor of ab and cd
(2) 4 is not a factor of ab and cd
[spoiler]Answer: B[/spoiler]
