it looks like you raised one of your parenthesis
does that mean t/30) should also be raised?

\[\frac{10}{11}=(\frac{75}{110})^{\frac{t}{30}}\]
take natural log of both sides
so then we can write
\[\ln(\frac{10}{11})=\frac{t}{30} \ln(\frac{75}{110})\]

remember: \[\ln(x^r)=r \ln(x)\]
\[30 \cdot \ln(\frac{10}{11}) \cdot \frac{1}{\ln(\frac{75}{110})}=t\]

\[30 \cdot \ln(\frac{10}{11}) \cdot \frac{1}{\ln(\frac{75}{110})}= 30 \cdot \frac{\ln(\frac{10}{11})}{\ln(\frac{75}{110})}\]
