Thread: solve my limit problem

Calculate lim of〖xe^(-x) 〗when (x→∞ ) using an appropriate rule and proves that it exist and it is equals to zero.
Help me solving this problem!

Clarification: do the weird brackets around xe^(-x) mean anything?

nope, sorry for that. the question is...
Calculate lim of [xe^(-x)] when (x→∞ ) using an appropriate rule and proves that it exist and it is equals to zero.

Use L'Hopitals rule after rewriting as:
