jika [tex]( \frac{1}{3} ) {}^{2x} = 27[/tex] maka nilai x adalah [tex]tolong \: ya \: pakek \: cra \: [/tex]

[tex] ( {3}^{ - 1} ) {}^{2x} = {3}^{3} \\ \\ {3}^{ - 2x} = {3}^{3} \\ \\ - 2x = 3 \\ \\ x = - \frac{3}{2}[/tex]

[tex]( { \frac{1}{3} })^{2x} = {3}^{3 } = ( { \frac{1}{3} })^{ - 3} \\ 2x = - 3 \\ x = - \frac{3}{2} [/tex]
semoga bermanfaat.
