To simplify the expression $5 \log x - (3 \log y + \log z)$, we can use logarithmic properties:

1. Use the property $a \log b = \log b^a$: $5 \log x = \log x^5$

2. Rewrite the subtraction using the property $\log a - \log b = \log \frac{a}{b}$: $3 \log y + \log z = \log(y^3) + \log z = \log(y^3 z)$

3. Now substitute back into the expression: $5 \log x - (3 \log y + \log z) = \log x^5 - \log(y^3 z)$

4. Use the subtraction property again: $= \log \frac{x^5}{y^3 z}$

So, the simplified expression is: $\log \frac{x^5}{y^3 z}$
