$\text{2 × $3^{x}$ = 10 × $3^{12}$ - 4 × $27^{4}$}$
$\text{2 × $3^{x}$ = 10 × $3^{12}$ - 4 × $(3^3)^{4}$}$
$\text{2 × $3^{x}$ = 10 × $3^{12}$ - 4 × $3^{12}$}$
$\text{2 × $3^{x}$ = $3^{12}$ × (10 - 4)}$
$\text{2 × $3^{x}$ = $3^{12}$ × 6}$
$\text{2 × $3^{x}$ = 531 441 × 6}$
$\text{2 × $3^{x}$ = 3 188 646}$
$\text{$3^{x}$ = 3 188 646 ÷ 2}$
$\text{$3^{x}$ = 1 594 323}$
$\text{$3^{x}$ = $3^{13}$ }$
$\text{⇒ x = 13}$
$\text{Vậy x = 13}$
