Best Answer: log 0 is impossiible .It's not defined.It's like 0/0. e raise to the power infinity is also not defined However log 0 can be any real value and e raise to the power infinity is infinity. just like we say 6/0 =infinity.Source(s): Super Ego.ating Newest Oldest.

Thus, when a number to some power is raised to a power again, we multiply the two powers to get the resultant value: (23)2 = 2(3) Ã (2) = 26. Finally, one more important piece of knowledge about exponents: a number raised to the power of zero is alwasy equal to 1. Thus: 20 = 130= -40 = 1.
