I seek clarification.... as per the attachment 2^(4-1)^2 is different from (2^(4-1))^2 ...right? The answer of the latter is going to be 2^5...is it? Yes, you're correct. 2^[(4 - 1)^2] = 2^9 ...... BUT ...... [2^(4 - 1)]^2 = 2^6 In this case, we just need to watch out for the parathesis then. The p...

Hi, Can anyone elaborately explain this answer? I haven't understood the approach as none of the solution turns up true. I tried testing with x=1 and then x=2
Thanks

Although I agree with the explanation as I too was stuck between D & E..... if we were to pick an answer I would go with "D" as an answer because in my opinion "within" can be used only if you have a "time range" and foreseeable future does not define any time range...

Is this a good GMAT quality question? I would pick A too... as it is the only one related to the topic. It thus stands out. But is this a good question?

INTUITION in DS - Experts...please comment.
