Express one logarithmic quantity in terms of another
Let \(r=\log_{3}\left(t\right)\). The variable \(t\) is positive. The base \(3\) and every displayed logarithm base are positive and are not 1
\[-9\log_{\left(3\right)^{3}}\left(\left(3\right)\,t^{-2}\right)\]
The displayed relation may be used in either logarithmic or exponential form
