What is $0^0$ ?
I have read many debates about this question. The debate has been going on at least since the early 19th century. At that time, most mathematicians agreed that $0^0$ = 1, until in 1821 Cauchy listed $0^0$ along with expressions like $\frac{0}{0}$ in a table of undefined forms.
On Wikipedia, there is a thread for the same.
On Quora, i read a discussion about the same.
The question is not to explain for $0^0$=1 or $0^0$=0 or it is undefined.
What sholuld we conclude for defining $0^0$ ?
