calculus - Computing limlimitsxtoinftyln(x)cdotln(1ex)

Limit as x approaches infinity of ln(x)ln(1ex):
limxln(x)ln(1ex)



The only thing I can think to do is rewrite the ln(x) on the bottom as (lnx)1 and use L’Hôpital’s rule, but I’ve done two iterations now and it keeps getting back to the 0/0 or infinity*0 indeterminate case. Any help on how to proceed will be much appreciated! Thanks

How to find limh0sin(ha)h without lhopital rule? I know when I use lhopital I easy get $$ \lim_{h\rightarrow 0}...
