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