$\frac{\log_{b} (9)}{\log_{b} (7)}$

Rewrite $\log_{b} (9)$ as $\log_{b} (3^{2})$ .

$\frac{\log_{b} (3^{2})}{\log_{b} (7)}$

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

$\frac{2 \log_{b} (3)}{\log_{b} (7)}$

$[\begin{array}{c} x^{2} & \frac{1}{2} \\ \sqrt{π} & \int x d x \end{array}]$
