Step 1.2.1

Reorder $\log (x - y)$ and $\frac{1}{6}$ .

$12 (\log ({(x + y)}^{\frac{1}{2}}) - (\frac{1}{6} \log (x - y)))$

Step 1.2.2

Simplify $\frac{1}{6} \log (x - y)$ by moving $\frac{1}{6}$ inside the logarithm.

$12 (\log ({(x + y)}^{\frac{1}{2}}) - \log ({(x - y)}^{\frac{1}{6}}))$

Step 2

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

$12 \log (\frac{{(x + y)}^{\frac{1}{2}}}{{(x - y)}^{\frac{1}{6}}})$

Step 3

Simplify $12 \log (\frac{{(x + y)}^{\frac{1}{2}}}{{(x - y)}^{\frac{1}{6}}})$ by moving $12$ inside the logarithm.

$\log ({(\frac{{(x + y)}^{\frac{1}{2}}}{{(x - y)}^{\frac{1}{6}}})}^{12})$

Step 4

Apply the product rule to $\frac{{(x + y)}^{\frac{1}{2}}}{{(x - y)}^{\frac{1}{6}}}$ .

$\log (\frac{{({(x + y)}^{\frac{1}{2}})}^{12}}{{({(x - y)}^{\frac{1}{6}})}^{12}})$

Step 5.2.1

Factor $2$ out of $12$ .

$\log (\frac{{(x + y)}^{\frac{1}{2} \cdot (2 (6))}}{{({(x - y)}^{\frac{1}{6}})}^{12}})$

Step 5.2.2

Cancel the common factor.

$\log (\frac{{(x + y)}^{\frac{1}{2} \cdot (2 \cdot 6)}}{{({(x - y)}^{\frac{1}{6}})}^{12}})$

Step 5.2.3
