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