**1. Homework Statement**

How can I fount the following limit using L'H'opetal rule?

$$\lim_{x\rightarrow+\infty}(ln(2x)-ln(x-4))$$

**2. Homework Equations**

**3. The Attempt at a Solution**

I tried to use the low

$$\lim_{x\rightarrow a} f(x)=\lim_{x\rightarrow a}e^{ln(f(x))}=e^l$$

But it seems to be useless

Many thanks for Help,.
