According to some Calculus textbooks, 0^0 is an "indeterminate form." What mathematicians mean by "indeterminate form" is that in some cases we think about it as having one value, and in other cases we think about it as having another.
which is slightly different than what ariels says. I guess I think 1994 is recent, but the real discussion took place in the 19th century...

However, read the link, don't let us read it for you.
