thanks everyone for solving the equations. However, my issue was not really "solving" each of the equations but solving the problem i.e. deriving the conclusion. As I mentioned, I was able to derive Given: x < or = 3 (i.e. 3,2,1....) statement 1) derives finally that x > or = 3 (i.e. 3,4,5...

thanks Anurag, Brent and GMATGuruNY. GMATGuruNY - thanks for getting to reasoning, as that's what exactly I was looking for. But, somehow, I am still not able to get step #2 Add 1 to each exponent.
