Hi Bunuel, Thanks for this question. I agree with the solution provided. Concerning the old debate whether 0^2=1 or 0^2=0, could it be assumed that for the purposes of the GMAT 0^2=0. With regards to this question this could change the answer substantially, as if not, it could mean that in (2) p and q can b both 0 and 1, and so the sanswer would be (E). Thank you!

Thank you! There is no debate whatsoever: 0^(positive) = 0, for example, 0^2 = 0. (anything but 0)^0 = 1, for example, 3^0 = 1. 0^0 is undefined and not tested on the GMAT. For the question at hand none of the variables can be 0, because we are told that p, q, and r are positive numbers, while 0 is neither positive nor negative. Hope it helps.

Got it! Thanks so much! Seems I was wrong based on some other old discussions. 0^(any positive) = 0 3^0 = 1. 0^0 is undefined and not tested on the GMAT

What if p = 2 q= 2 and r=\(\sqrt{2}\), then these values are not equal?

I observed in another problem whose equation is as follows, q^2  r^2 = 0
In that problem, it was said q cannot be equal to r, since the equation can be further reduced to q  r = 0.
Does it apply here as well?

q2=r2 if q =  2 and r = 2 than both are 4, but are not the same, or am I wrong?
Than the answer must be E
