$\log (\frac{\sqrt[3]{x^{4} z^{2}}}{y^{4}})$

Step 1

Rewrite $\log (\frac{\sqrt[3]{x^{4} z^{2}}}{y^{4}})$ as $\log (\sqrt[3]{x^{4} z^{2}}) - \log (y^{4})$ .

$\log (\sqrt[3]{x^{4} z^{2}}) - \log (y^{4})$

Step 2

Use $\sqrt[n]{a^{x}} = a^{\frac{x}{n}}$ to rewrite $\sqrt[3]{x^{4} z^{2}}$ as ${(x^{4} z^{2})}^{\frac{1}{3}}$ .

$\log ({(x^{4} z^{2})}^{\frac{1}{3}}) - \log (y^{4})$

Step 3

Expand $\log ({(x^{4} z^{2})}^{\frac{1}{3}})$ by moving $\frac{1}{3}$ outside the logarithm.

$\frac{1}{3} \log (x^{4} z^{2}) - \log (y^{4})$

Step 4

Expand $\log (y^{4})$ by moving $4$ outside the logarithm.

$\frac{1}{3} \log (x^{4} z^{2}) - (4 \log (y))$

Step 5

Multiply $4$ by $- 1$ .

$\frac{1}{3} \log (x^{4} z^{2}) - 4 \log (y)$

Step 6

Rewrite $\log (x^{4} z^{2})$ as $\log (x^{4}) + \log (z^{2})$ .

$\frac{1}{3} (\log (x^{4}) + \log (z^{2})) - 4 \log (y)$

Step 7

Expand $\log (x^{4})$ by moving $4$ outside the logarithm.

$\frac{1}{3} (4 \log (x) + \log (z^{2})) - 4 \log (y)$

Step 8

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

$\frac{1}{3} (4 \log (x) + 2 \log (z)) - 4 \log (y)$
