Is there a typo here?
Looks like they all have at least one solution. Possible solutions are:
A. n=2
B. n=-2
C. n=-2/3
D. n=0
E. n=0

Interesting.
When you select the quote option, you can see the question as it was entered, but once you review the post, several characters are changed.
The original question is:

Each of the following equations has at least one solution EXCEPT
-2n = (-2)-n
2-n = (-2)n
2n = (-2)-n
(-2)n = -2n
(-2)-n = -2-n

Hi Brent,

the answer is given as first option

i.e

-2 power n = (-2) power -n

solution says in this scenario, both sides are not equal even when n = 0 because,

-2 power n = -1 * 2 power 0 = -1 * 1 = -1

(-2) power -n = (-2) power 0 = 1

On another thread also,i found a similar problem-https://www.beatthegmat.com/absolute-val ... tml#219747
I don't know what is the cause behind it but I think this is a matter of concern and should be immediately brought to the notice of BEAT THE GMAT TEAM.

Hi harsh.champ,

That was posted 10 days back. Now this problem is not coming in this post as well. It is fixed across the whole system now.
