What is the greatest possible value of X?
1) X is an integer 2) 6<x<7 the solution is both statement are needed. Why statement 2 isn't sufficient by itself? i mean in that case the greatest possible value of x = 6,9 since nothing in the problem says that x has to be an integer? I obviously miss something here. please help, anyone. thx

Hi David, Well the latest GMAT prep I took, I had 620 (Q44 V30). The one before, 640 (Q49 V28). As you see, verbal is my weakness... I had a very bad verbal score and underperformed math on D day.

Number raised to 0 power
Hi,
Can someone confirms that 2^-0 is not 2/0 but rather 1 just as per 2^0?
Each of the following equations has at least one solution EXCEPT
–2^n = (–2)^-n
2^-n = (–2)^n
2^n = (–2)^-n
(–2)^n = –2^n
(–2)^-n = –2^-n
Answer is a.
Thx
