$2^{4}$ . $8^{3}$ = $2^{4}$ . $(2³)^{3}$ = $2^{4}$ . $2^{9}$ = $2^{13}$
$125^{3}$ : $25^{2}$ = $(5³)^{3}$ : $(5²)^{2}$ = $5^{9}$ : $5^{4}$ = $5^{5}$
$2^{24}$ : $4^{6}$ = $2^{24}$ : $(2²)^{6}$ = $2^{24}$ : $2^{12}$ = $2^{12}$
$3^{2}$ .$\frac{27^{4} }{ 9^{3} }$ = $3^{2}$ . $\frac{(3³)^{4} }{ (3²)^{3} }$
= $3^{2}$ . $\frac{3^{12} }{ 3^{6} }$ = 9 . 2 = 18
Xin hay nhất nha :)
