$\log (x^{2} y^{3} \sqrt[3]{x^{2} y^{5}})$

Step 1

Rewrite $\log (x^{2} y^{3} \sqrt[3]{x^{2} y^{5}})$ as $\log (x^{2} y^{3}) + \log (\sqrt[3]{x^{2} y^{5}})$ .

$\log (x^{2} y^{3}) + \log (\sqrt[3]{x^{2} y^{5}})$

Step 2

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

$\log (x^{2}) + \log (y^{3}) + \log (\sqrt[3]{x^{2} y^{5}})$

Step 3

Use $\sqrt[n]{a^{x}} = a^{\frac{x}{n}}$ to rewrite $\sqrt[3]{x^{2} y^{5}}$ as ${(x^{2} y^{5})}^{\frac{1}{3}}$ .

$\log (x^{2}) + \log (y^{3}) + \log ({(x^{2} y^{5})}^{\frac{1}{3}})$

Step 4

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

$2 \log (x) + \log (y^{3}) + \log ({(x^{2} y^{5})}^{\frac{1}{3}})$

Step 5

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

$2 \log (x) + 3 \log (y) + \log ({(x^{2} y^{5})}^{\frac{1}{3}})$

Step 6

Expand $\log ({(x^{2} y^{5})}^{\frac{1}{3}})$ by moving $\frac{1}{3}$ outside the logarithm.

$2 \log (x) + 3 \log (y) + \frac{1}{3} \log (x^{2} y^{5})$

Step 7

Rewrite $\log (x^{2} y^{5})$ as $\log (x^{2}) + \log (y^{5})$ .

$2 \log (x) + 3 \log (y) + \frac{1}{3} (\log (x^{2}) + \log (y^{5}))$

Step 8

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

$2 \log (x) + 3 \log (y) + \frac{1}{3} (2 \log (x) + \log (y^{5}))$

Step 9

Expand $\log (y^{5})$ by moving $5$ outside the logarithm.
