$\ln (\ln (e^{e^{200}}))$

Step 1

Expand $\ln (e^{e^{200}})$ by moving $e^{200}$ outside the logarithm.

$\ln (e^{200} \ln (e))$

Step 2

Rewrite $\ln (e^{200} \ln (e))$ as $\ln (e^{200}) + \ln (\ln (e))$ .

$\ln (e^{200}) + \ln (\ln (e))$

Step 3

Use logarithm rules to move $200$ out of the exponent.

$200 \ln (e) + \ln (\ln (e))$

Step 4

The natural logarithm of $e$ is $1$ .

$200 \cdot 1 + \ln (\ln (e))$

Step 5

Multiply $200$ by $1$ .

$200 + \ln (\ln (e))$
