$\log_{9} (\sqrt{3})$

Step 1

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

$\log_{9} (3^{\frac{1}{2}})$

Step 2

Expand $\log_{9} (3^{\frac{1}{2}})$ by moving $\frac{1}{2}$ outside the logarithm.

$\frac{1}{2} \log_{9} (3)$

Step 3

Logarithm base $9$ of $3$ is $\frac{1}{2}$ .

$\frac{1}{2} \cdot \frac{1}{2}$

Step 4

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