Solving an Indeterminate Limit with L'Hospital's Rule

[student85]

Homework Statement

find the limit:

lim (lnx)^3 / x
x-->(infinity)

Homework Equations

It's a L´hospital homework so that should be what I need to use.

The Attempt at a Solution

However, when using L'Hospital, I get nowhere since I keep getting indeterminations.
Help is appreciated.

You'll have to repeatedly use L'Hopital until you get to a non-indeterminant. Takes 4 times, I think.

Thanks.

Nasty how? It's just a little repetitious.
