Expand natural log of 6e- natural log of 42+ natural log of 7e

$\ln (6 e) - \ln (42) + \ln (7 e)$

Rewrite $\ln (6 e)$ as $\ln (6) + \ln (e)$ .

$\ln (6) + \ln (e) - \ln (42) + \ln (7 e)$

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

$\ln (6) + 1 - \ln (42) + \ln (7 e)$

Rewrite $\ln (7 e)$ as $\ln (7) + \ln (e)$ .

$\ln (6) + 1 - \ln (42) + \ln (7) + \ln (e)$

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

$\ln (6) + 1 - \ln (42) + \ln (7) + 1$

Simplify each term.

Rewrite $\ln (6)$ as $\ln (2 (3))$ .

$\ln (2 (3)) + 1 - \ln (42) + \ln (7) + 1$

Rewrite $\ln (2 (3))$ as $\ln (2) + \ln (3)$ .

$\ln (2) + \ln (3) + 1 - \ln (42) + \ln (7) + 1$

Rewrite $\ln (2 \cdot 3 \cdot 7)$ as $\ln (2 \cdot 3) + \ln (7)$ .

$\ln (2) + \ln (3) + 1 - (\ln (2 \cdot 3) + \ln (7)) + \ln (7) + 1$

Rewrite $\ln (2 \cdot 3)$ as $\ln (2) + \ln (3)$ .

$\ln (2) + \ln (3) + 1 - (\ln (2) + \ln (3) + \ln (7)) + \ln (7) + 1$

Apply the distributive property.

$\ln (2) + \ln (3) + 1 - \ln (2) - \ln (3) - \ln (7) + \ln (7) + 1$

Subtract $\ln (2)$ from $\ln (2)$ .

$0 + \ln (3) + 1 - \ln (3) - \ln (7) + \ln (7) + 1$

Subtract $\ln (3)$ from $\ln (3)$ .

$0 + 0 + 1 - \ln (7) + \ln (7) + 1$

Add $- \ln (7)$ and $\ln (7)$ .

$0 + 0 + 1 + 0 + 1$

Add $0$ and $0$ .

$0 + 1 + 0 + 1$

Add $0$ and $1$ .

$1 + 0 + 1$

Add $1$ and $0$ .

$1 + 1$

Add $1$ and $1$ .

$2$
