Step 1.2.1.1.1

Raise $x$ to the power of $1$ .

$\log_{6} (x^{1} x^{2}) + \ln (e) = 2$

Step 1.2.1.1.2

Use the power rule $a^{m} a^{n} = a^{m + n}$ to combine exponents.

$\log_{6} (x^{1 + 2}) + \ln (e) = 2$

Step 1.2.1.2

Add $1$ and $2$ .

$\log_{6} (x^{3}) + \ln (e) = 2$

Step 1.2.2

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