The logarithmic equation given is,


\log _4\left(11x\right)=2

Apply log rules


\log_4\left(11x\right)=\log_42^4

Cancel out the log₄


11x=2^4

Solve for x


\begin{gathered} 11x=16 \\ Divide\text{ both sides by 11} \\ (11x)/(11)=(16)/(11) \\ x=(16)/(11)=1(5)/(11) \end{gathered}

Hence, the solution set is


x=(16)/(11)or1(5)/(11)
