#### Answer

$\log (\frac{x^2y}{z})$

#### Work Step by Step

We can combine $2$$\log x$ + $\log y$ - $\log z$ to get ___________
We first use the third law to $2$$\log x$, so:
$\log x^2$ + $\log y$ - $\log z$
Use the first law for $\log x^2$ + $\log y$
$\log x^2y$ - $\log z$
Use the second law for $\log x^2y$ - $\log z$
$\log (\frac{x^2y}{z})$
