Answer 1

Step-by-step explanation:

1.

$= \frac{8}{27}^{2} \times { \frac{9}{4} }^{2} \div { \frac{2}{3} }^{4} \\ = {( \frac{72}{108} )}^{2} \div { \frac{2}{3} }^{4} \\ = { \frac{2}{3} }^{2} \div { \frac{2}{3} }^{4} \\ = { \frac{2}{3} }^{2 - 4} \\ = { \frac{2}{3} }^{ - 2} \\ = { \frac{3}{2} }^{2}$

$\frac{9}{4}$

2.

$= { \frac{4}{3} }^{5 + 7} \\ = { \frac{4}{3} }^{12}$
