what is n to raise power infinity

I'll just add to Ninja's answer.

I think that a minus number raised to infinity would be undefined.

A positive number between 0 and 1 raised to infinity would be 0

A positive number greater than 1 raised to infinity would be infinity

Here is a graph.

$$\begin{array}{l} \mbox{Depends on what n is.}\\ \mbox{If $n = 0$, then $n^\infty = 0$}\\ \mbox{If $n = 1$, then $n^\infty = 1$}\\ \mbox{If n equals anything else though, I believe the answer would be infinity.} \end{array}$$

$$\mbox{This\;is\;just\;an\;example.}\\\\n^\infty\\\\=2^\infty\\\\=\infty$$

Great answer, Melody. I didn't know that. This is my basic knowledge.

But, thanks, Melody!

That is excellent Dragon.
