\sf{\underline{\underline{\large{\bold{Solution}}}}}

⠀⠀⠀

\sf :\longrightarrow \:{\bold{2^{3x-5}\times a^{x-2} = 2^{x-2}\times a^{1-x} }}

⠀⠀⠀⠀

\sf : \longrightarrow \: {\bold{\dfrac{ 2^{3x-5}}{2^{x-2}} = \dfrac{a^{1-x}}{a^{x-2}} }}

⠀⠀⠀⠀

  • If the bases are same the power is subtracted in division .

⠀⠀⠀⠀

\sf :\longrightarrow \:{\bold{2^{3x-5 - x + 2 } =  a^{1-x - x + 2} }}

⠀⠀⠀⠀

\sf :\longrightarrow \:{\bold{2^{2x-3}= a^{3-2x} }}

⠀⠀⠀⠀

\sf :\longrightarrow \:{\bold{2^{2x-3}= a^{- (2x-3)} }}

⠀⠀⠀⠀

\sf :\longrightarrow \:{\bold{2^{2x-3}= \bigg( \dfrac{1}{a}\bigg)^{2x-3}}}

⠀⠀⠀⠀

  • If the powers are equal then the base will also be equal

⠀⠀⠀⠀

\sf :\longrightarrow \:{\bold{\dfrac{1}{a} = 2 }}

⠀⠀⠀⠀

\sf :\longrightarrow \:{\bold{a = \dfrac{1}{2}}}

⠀⠀⠀⠀
