$\log (12) + \frac{1}{2} \log (7) - \log (2)$

Step 1

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

$\frac{1}{2} \cdot \log (7) + \log (\frac{12}{2})$

Step 2

Simplify each term.

Step 2.1

Simplify $\frac{1}{2} \log (7)$ by moving $\frac{1}{2}$ inside the logarithm.

$\log (7^{\frac{1}{2}}) + \log (\frac{12}{2})$

Step 2.2

Divide $12$ by $2$ .

$\log (7^{\frac{1}{2}}) + \log (6)$

Step 3

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

$\log (7^{\frac{1}{2}} \cdot 6)$

Step 4

Move $6$ to the left of $7^{\frac{1}{2}}$ .

$\log (6 \cdot 7^{\frac{1}{2}})$

Step 5

The result can be shown in multiple forms.

Exact Form:

$\log (6 \cdot 7^{\frac{1}{2}})$

Decimal Form:

$1.20070027 \dots$
