$\log_{17} (\frac{\sqrt[5]{18}}{q^{2} p})$

Step 1

Rewrite $\log_{17} (\frac{\sqrt[5]{18}}{q^{2} p})$ as $\log_{17} (\sqrt[5]{18}) - \log_{17} (q^{2} p)$ .

$\log_{17} (\sqrt[5]{18}) - \log_{17} (q^{2} p)$

Step 2

Use $\sqrt[n]{a^{x}} = a^{\frac{x}{n}}$ to rewrite $\sqrt[5]{18}$ as $18^{\frac{1}{5}}$ .

$\log_{17} (18^{\frac{1}{5}}) - \log_{17} (q^{2} p)$

Step 3

Expand $\log_{17} (18^{\frac{1}{5}})$ by moving $\frac{1}{5}$ outside the logarithm.

$\frac{1}{5} \log_{17} (18) - \log_{17} (q^{2} p)$

Step 4

Rewrite $\log_{17} (18)$ as $\log_{17} (2 \cdot 3^{2})$ .

$\frac{1}{5} \log_{17} (2 \cdot 3^{2}) - \log_{17} (q^{2} p)$

Step 5

Rewrite $\log_{17} (2 \cdot 3^{2})$ as $\log_{17} (2) + \log_{17} (3^{2})$ .

$\frac{1}{5} (\log_{17} (2) + \log_{17} (3^{2})) - \log_{17} (q^{2} p)$

Step 6

Expand $\log_{17} (3^{2})$ by moving $2$ outside the logarithm.

$\frac{1}{5} (\log_{17} (2) + 2 \log_{17} (3)) - \log_{17} (q^{2} p)$

Step 7

Apply the distributive property.

$\frac{1}{5} \log_{17} (2) + \frac{1}{5} (2 \log_{17} (3)) - \log_{17} (q^{2} p)$

Step 8

Combine $\frac{1}{5}$ and $\log_{17} (2)$ .

$\frac{\log_{17} (2)}{5} + \frac{1}{5} (2 \log_{17} (3)) - \log_{17} (q^{2} p)$

Step 9

Multiply $\frac{1}{5} (2 \log_{17} (3))$ .

Step 9.1

Combine $2$ and $\frac{1}{5}$ .

$\frac{\log_{17} (2)}{5} + \frac{2}{5} \log_{17} (3) - \log_{17} (q^{2} p)$

Step 9.2

Combine $\frac{2}{5}$ and $\log_{17} (3)$ .

$\frac{\log_{17} (2)}{5} + \frac{2 \log_{17} (3)}{5} - \log_{17} (q^{2} p)$

Step 10

Rewrite $\log_{17} (q^{2} p)$ as $\log_{17} (q^{2}) + \log_{17} (p)$ .

$\frac{\log_{17} (2)}{5} + \frac{2 \log_{17} (3)}{5} - (\log_{17} (q^{2}) + \log_{17} (p))$

Step 11

Expand $\log_{17} (q^{2})$ by moving $2$ outside the logarithm.

$\frac{\log_{17} (2)}{5} + \frac{2 \log_{17} (3)}{5} - (2 \log_{17} (q) + \log_{17} (p))$
