= \ \textgreater \  Given :  \frac{ 3^{5x} * 81^2 * 6561 }{ 3^{2x} } = 3^7

= \ \textgreater \   3^{5x} * 3^8 * 3^8 *  3^{-2x}  =  3^{7}

= \ \textgreater \   3^{5x - 2x} *  3^{8 + 8} =  3^{7}

= \ \textgreater \   3^{3x} *  3^{16} =  3^{7}

= \ \textgreater \   3^{3x} =  \frac{ 3^{7} }{ 3^{16} }

= \ \textgreater \   3^{3x} =  3^{7 - 16}

= \ \textgreater \   3^{3x} =  3^{-9}

= > 3x = -9

= > x = -3.



Hope this helps!
