    hint: \[\huge \log_5 (125) \implies \log_5 (5^3) \implies 3\] \[\huge \log_{\frac 15} (5) \implies \log_{(5^{-1})} (5^{-1})^{-1} \implies -1\] does that help?

    \[\Large \log_5 125 + 3^{\log_5 125} + 3 \log_{\frac 15} 5\] using the ones i said this will give you \[\large 3 + 3^3 + 3(-1)\] do yoou see it now?
