ln (ln e^e)

I don't remember how to change it, and all I know is that the answer is 1. If anyone can help, it will be very useful. :3

$\ln (\ln e^e)$

$=\ln (e\ln e)$

$=\ln (e\times 1)$

$=\ln (e)$

$=1$

$ln (ln e^e)=?$

First the inside expression: $(ln e^e)=elne=e\cdot 1=e$

Now, $ln(ln e^e)=ln e=1$
