2 digits integer with length=6
2^6 = 64
2^5*3 = 96
3^6 = 729
2^4*3^2 =144
2^3*3^3 = 27*8 = 216
2^2*3^4 >216
thus two (64 and 96)

Hi Divya,

while I appreciate your enthusiasm for getting your questions posted as quickly as possible, I'm sure that I speak for all BTG users when I say we'd appreciate it even more if you'd slow down a bit and proofread your posts - there are so many typos and abbreviations that it's almost impossible to determine the actual question.

The best way to prepare for the GMAT is to practice questions that are as similar as possible to those that you'd find on the test; since the GMAT always uses proper English (and full sentences), practice questions should be expressed in that form as well.

Thanks!
