[tex]\color{thistle}{\bf{x = ....?}}[/tex]
Penjelasan dengan langkah-langkah:
[tex]\sf{9}^{4x + 8} = {81}^{x - 3}[/tex]
[tex]\sf {9}^{4x + 8} = ( {9}^{2} ) {}^{x - 3} [/tex]
[tex]\sf {9}^{4x + 8} = {9}^{2x - 6} [/tex]
[tex]\sf4x + 8 = 2x - 6[/tex]
[tex]\sf4x - 2x = - 6 - 8[/tex]
[tex]\sf2x = - 14[/tex]
[tex]\sf \: x = - \frac{ 14}{2} [/tex]
[tex]\sf \: x = - 7[/tex]
