### the natural exponential

Question 1:
Use lim n->inf (1+1/n) = e or its variation and logarithm to prove lim n->inf (1+x/n) = e^x for all x.

Again I got confused when you put an exponent on the (1+X/n) side.
It was assumed that your post had erroneously omitted the exponent, since of course the expression will not lead to the natural exponential without said exponent. For further information, kindly consult resources such as this. If your text or your instructor is not using the standard expression (as displayed at the link), then kindly please reply with documentation of whatever non-standard methodology is being required of you. Thank you.

I will email him and find out if there is supposed to be an exponent on that. It makes no sense why everything I have looked up and what you have posted has it and yet his does not.

Any idea about the other question or would it be wise to actually put that in its own post?
