\underline{\textbf{Given:}}

\mathsf{3^{2x-1}{\times}4^{x-1}=36}

\underline{\textbf{To find:}}

\textsf{The value of x}

\underline{\textbf{Solution:}}

\mathsf{3^{2x-1}{\times}4^{x-1}=36}

\textsf{This can be written as}

\mathsf{3^{2x-1}{\times}(2^2)^{x-1}=9{\times}4}

\mathsf{3^{2x-1}{\times}2^{2x-2}=3^2{\times}2^2}

\textsf{Equating powers of corresponding factors on bothsides, we get}

\mathsf{2x-1=2\;\;and\;\;2x-2=2}

\mathsf{2x=2+1\;\;and\;\;2x=2+2}

\mathsf{2x=3\;\;and\;\;2x=4}

\mathsf{x=\dfrac{3}{2}\;\;and\;\;x=2}

\therefore\underrline{\mathsf{The\;value\;of\;x\;are\;\dfrac{3}{2}\;and\;2}}

\underline{\textbf{Find more:}}
