$\frac{1}{3} \cdot \log_{2} (x - 6) - 4 \log_{2} (z) + 2 \log_{3} (y)$

Step 1

Combine $\frac{1}{3}$ and $\log_{2} (x - 6)$ .

$\frac{\log_{2} (x - 6)}{3} - 4 \log_{2} (z) + 2 \log_{3} (y)$

Step 2

To write $- 4 \log_{2} (z)$ as a fraction with a common denominator, multiply by $\frac{3}{3}$ .

$\frac{\log_{2} (x - 6)}{3} - 4 \log_{2} (z) \cdot \frac{3}{3} + 2 \log_{3} (y)$

Step 3

Combine $- 4 \log_{2} (z)$ and $\frac{3}{3}$ .

$\frac{\log_{2} (x - 6)}{3} + \frac{- 4 \log_{2} (z) \cdot 3}{3} + 2 \log_{3} (y)$

Step 4

Combine the numerators over the common denominator.

$\frac{\log_{2} (x - 6) - 4 \log_{2} (z) \cdot 3}{3} + 2 \log_{3} (y)$

Step 5

Multiply $3$ by $- 4$ .

$\frac{\log_{2} (x - 6) - 12 \log_{2} (z)}{3} + 2 \log_{3} (y)$
