real analysis - How to evaluate the following limit




How can I determine the following limitlimnln(n)nx

where x[2,)



WolframAlpha tells me the limit is 0, but I am not sure how to go about calculating it manually, I suspect L'Hospital plays a role?

limnlnnnx=limn1/nxnx1=1xlimn1nx=0



when x>0
