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.
