$\log (\frac{\sqrt{x^{2} y^{3}}}{z})$

Step 1

Rewrite $\log (\frac{\sqrt{x^{2} y^{3}}}{z})$ as $\log (\sqrt{x^{2} y^{3}}) - \log (z)$ .

$\log (\sqrt{x^{2} y^{3}}) - \log (z)$

Step 2

Use $\sqrt[n]{a^{x}} = a^{\frac{x}{n}}$ to rewrite $\sqrt{x^{2} y^{3}}$ as ${(x^{2} y^{3})}^{\frac{1}{2}}$ .

$\log ({(x^{2} y^{3})}^{\frac{1}{2}}) - \log (z)$

Step 3

Expand $\log ({(x^{2} y^{3})}^{\frac{1}{2}})$ by moving $\frac{1}{2}$ outside the logarithm.

$\frac{1}{2} \log (x^{2} y^{3}) - \log (z)$

Step 4

Rewrite $\log (x^{2} y^{3})$ as $\log (x^{2}) + \log (y^{3})$ .

$\frac{1}{2} (\log (x^{2}) + \log (y^{3})) - \log (z)$

Step 5

Expand $\log (x^{2})$ by moving $2$ outside the logarithm.

$\frac{1}{2} (2 \log (x) + \log (y^{3})) - \log (z)$

Step 6

Expand $\log (y^{3})$ by moving $3$ outside the logarithm.

$\frac{1}{2} (2 \log (x) + 3 \log (y)) - \log (z)$
