Answer:


\qquad\quad {:}\leadsto\sf {3}^{\frac {x}{2}}* {3}{}^{\frac {x}{4}}=3^6


\qquad\quad {:}\leadsto\sf 3{}^{\frac {x}{2}+\frac {x}{4}}=3^6


\qquad\quad {:}\leadsto\sf 3 {}^{\frac {2x+x}{4}}=3^6


\qquad\quad {:}\leadsto\sf 3 {}^{\frac {3x}{4}}=3^6


\qquad\quad {:}\leadsto\sf \frac {3x}{4}=6

  • Use cross multiplication method


\qquad\quad {:}\leadsto\sf 3x=24


\qquad\quad {:}\leadsto\sf x=\frac {24}{3}


\qquad\quad {:}\leadsto\sf x=8
