$\ln (\frac{6}{e^{2}})$

Step 1

Move $e^{2}$ to the numerator using the negative exponent rule $\frac{1}{b^{n}} = b^{- n}$ .

$\ln (6 e^{- 2})$

Step 2

Rewrite $\ln (6 e^{- 2})$ as $\ln (6) + \ln (e^{- 2})$ .

$\ln (6) + \ln (e^{- 2})$

Step 3

Use logarithm rules to move $- 2$ out of the exponent.

$\ln (6) - 2 \ln (e)$

Step 4

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

$\ln (6) - 2 \cdot 1$

Step 5

Multiply $- 2$ by $1$ .

$\ln (6) - 2$
