I think there is a lot of confusion on limits due to a post on forum

let us do the following problems...

Find the following

\\1) \lim_{x\rightarrow 1} (x^{n}) \\ \\2) \lim_{x\rightarrow 1^+} (x^{n}) \\ \\3) \lim_{x\rightarrow 1^-} (x^{n}) \\ \\4) \lim_{n\rightarrow \infty}\lim_{x\rightarrow 1^-} (x^{n}) \\ \\5) \lim_{n\rightarrow \infty}\lim_{x\rightarrow 1^+} (x^{n}) \\ \\6) \lim_{n\rightarrow \infty}\lim_{x\rightarrow 1} (x^{n}) \\ \\7) \lim_{n\rightarrow \infty, x\rightarrow 1^+} (x^{n}) \\ \\8) \lim_{n\rightarrow \infty, x\rightarrow 1^-} (x^{n}) \\ \\9) \lim_{n\rightarrow \infty, x\rightarrow 1} (x^{n}) \\ \\10) \lim_{x\rightarrow 1^+}\lim_{n\rightarrow \infty} (x^{n}) \\ \\11) \lim_{x\rightarrow 1^-}\lim_{n\rightarrow \infty} (x^{n}) \\ \\12) \lim_{x\rightarrow 1}\lim_{n\rightarrow \infty} (x^{n}) \\
