Good question. I thought it is 1. But not for sure. I will wait for other answers.

I might be wrong, but I think I remember reading that the GMAT stays away from 0^0.

0^0, in some sources equals to 1, some mathematicians say it's undefined. You won't need this for GMAT.

During the past decade, mathematicians argued extensively about the value of 0^0. Some answer that 0^0 = 1, while others answer that 0^0 is undefined. In the unlikely event that this question appears in some format or is a required intermediary calculation, the correct answer is more likely that 0^0 = 1.

and:
Note: the case of 0^0 is not tested on the GMAT.

Hope it helps.

So what about the structure x^y in a data sufficiency problem?

How would we consider the possibility of x and y being 0?

At least one of x and y would be given non-zero. Since GMAT doesn't test it, they will ensure that you don't have to take a call on the value of 0^0.

Technically 0^0 is 1.... Not sure gmat wise though. I had the same question with 0 times 0 which is in gmat terms = to 0, but I think its more complicated than that.

0*0=0.

Hi,

Consider the following equation,
\(a^m/a^n = a^(m-n)\)
we say \(a^0 = 1\), 'casuse \(a^0 = a/a\) \(|a|>0\)
so, \(0^0\) would take form of \(0/0\), which is not defined.

Also, please note that infinity and not defined (nd) are to different terms.

1/0 = infinity
(infinity x 0), (0/0) etc. are not defined.

Anyways, no one has to worry about n.d. forms as they are out of scope for GMAT.
