nhanh hộ mình mình cần gấp ạ

$h)\frac{25^7 \times(0.32)^{16}}{20^{14} \times (0.08)^{17}}$

$=\frac{(5\times5)^7 \times (0.4\times0.8)^{16}}{(4\times5)^14 \times (0.2\times0.4)^{17}}$

$=\frac{5^{7+7}\times0.4^{16}\times0.8^{16}}{4^{14}\times5^{14}\times0.2^{17}\times0.4^{17}}$

$=\frac{5^{14}\times0.4^{16}\times0.8^{16}}{4^{14}\times5^{14}\times0.2^{17}\times0.4^{17}}$

$=\frac{0.8^{16}}{4^{14}\times0.2^{17}}$

$=\frac{(0.2\times4)^{16}}{4^{14}\times0.2^{17}}$

$=\frac{0.2^{16}\times4^{16}}{4^{14}\times0.2^{17}}$

$=\frac{4^2}{0.2^{17}}$

$=\frac{16}{0.2}$

$=80$
