$\log (8) - 2 \log (6) + \log (3)$

Step 1

Use the product property of logarithms, $\log_{b} (x) + \log_{b} (y) = \log_{b} (x y)$ .

$\log (8 \cdot 3) - 2 \log (6)$

Step 2

Step 2.1

Multiply $8$ by $3$ .

$\log (24) - 2 \log (6)$

Step 2.2

Simplify $- 2 \log (6)$ by moving $2$ inside the logarithm.

$\log (24) - \log (6^{2})$

Step 2.3

Raise $6$ to the power of $2$ .

$\log (24) - \log (36)$

Step 3

Use the quotient property of logarithms, $\log_{b} (x) - \log_{b} (y) = \log_{b} (\frac{x}{y})$ .

$\log (\frac{24}{36})$

Step 4

Cancel the common factor of $24$ and $36$ .
