$\ln (\sqrt[3]{z \sqrt{e}})$

Step 1

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

$\ln (\sqrt[3]{z e^{\frac{1}{2}}})$

Step 2

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

$\ln ({(z e^{\frac{1}{2}})}^{\frac{1}{3}})$

Step 3

Expand $\ln ({(z e^{\frac{1}{2}})}^{\frac{1}{3}})$ by moving $\frac{1}{3}$ outside the logarithm.

$\frac{1}{3} \ln (z e^{\frac{1}{2}})$

Step 4

Rewrite $\ln (z e^{\frac{1}{2}})$ as $\ln (z) + \ln (e^{\frac{1}{2}})$ .

$\frac{1}{3} (\ln (z) + \ln (e^{\frac{1}{2}}))$

Step 5

Expand $\ln (e^{\frac{1}{2}})$ by moving $\frac{1}{2}$ outside the logarithm.

$\frac{1}{3} (\ln (z) + \frac{1}{2} \ln (e))$

Step 6

The natural logarithm of $e$ is $1$ .

$\frac{1}{3} (\ln (z) + \frac{1}{2} \cdot 1)$

Step 7

Multiply $\frac{1}{2}$ by $1$ .

$\frac{1}{3} (\ln (z) + \frac{1}{2})$

Step 8

Apply the distributive property.

$\frac{1}{3} \ln (z) + \frac{1}{3} \cdot \frac{1}{2}$

Step 9

Combine $\frac{1}{3}$ and $\ln (z)$ .

$\frac{\ln (z)}{3} + \frac{1}{3} \cdot \frac{1}{2}$

Step 10

Multiply $\frac{1}{3} \cdot \frac{1}{2}$ .
