Recall the property of a logarithm which states that
[tex]\log \Big(\frac{x}{y}\Big)=\log x-\log y[/tex][tex]\begin{gathered} \text{Given that }\log \frac{\frac{1}{9}}{k} \\ \text{applying the property for logarithm, it is equivalent to} \\ \\ \log \frac{\frac{1}{9}}{k}=\log \frac{1}{9}-\log k \end{gathered}[/tex]
