Answer 2

${\huge{\underline{\underline{\rm{Answer\checkmark}}}}}$

$\longrightarrow \: ( \: \: {( \frac{2}{3}) }^{3} \times {( \frac{2}{3}) }^{ - 7} \: ) \div {( \frac{2}{ 3}) }^{4}$

$\mapsto \: ( {( \frac{2}{3}) }^{3 + - 7} ) \div {( \frac{2}{3}) }^{4}$

$\mapsto \: {( \frac{2}{3} )}^{ - 4} \div {( \frac{2}{3}) }^{4} \\ \\ \mapsto \: {( \frac{2}{3}) }^{ - 4 + 4} \\ \\ \implies \: {( \frac{2}{3}) }^{0} = 1$

★ Formula used -

$\star \: \: \rm \: {a}^{x} \times {a}^{y} = {a}^{x + y}$

$\star \: \: \rm \: {a}^{x} \div {a}^{y} = {a}^{x - y}$

$\star \: \: \rm \: {a}^{0} = 1$
