$\log_{3} (4) + 2 \log_{3} (\frac{1}{2}) + \log_{3} (x)$

Step 1

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

$2 \log_{3} (\frac{1}{2}) + \log_{3} (4 x)$

Step 2.1

Simplify $2 \log_{3} (\frac{1}{2})$ by moving $2$ inside the logarithm.

$\log_{3} ({(\frac{1}{2})}^{2}) + \log_{3} (4 x)$

Step 2.2

Apply the product rule to $\frac{1}{2}$ .

$\log_{3} (\frac{1^{2}}{2^{2}}) + \log_{3} (4 x)$

Step 2.3

One to any power is one.

$\log_{3} (\frac{1}{2^{2}}) + \log_{3} (4 x)$

Step 2.4

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

$\log_{3} (\frac{1}{4}) + \log_{3} (4 x)$

Step 3

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

$\log_{3} (\frac{1}{4} (4 x))$
