Step 1.1

The change of base rule can be used if $a$ and $b$ are greater than $0$ and not equal to $1$ , and $x$ is greater than $0$ .

$\frac{\log_{a} (x) = \frac{\log_{b} (x)}{\log_{b} (a)}}{\log (m)}$

Step 1.2

Substitute in values for the variables in the change of base formula, using $b = 10$ .

$\frac{\frac{\log (m)}{\log (9)}}{\log (m)}$

Step 2

Multiply the numerator by the reciprocal of the denominator.

$\frac{\log (m)}{\log (9)} \cdot \frac{1}{\log (m)}$

Step 3

Cancel the common factor of $\log (m)$ .
