Answer 2

Answer:

$\frac{16}{9}$

Step-by-step explanation:

$( { \frac{ -3}{4} )}^{3} \div ({ \frac { - 3}{4} )}^{5} \\ = \frac{ { (\frac{ - 3}{4}) }^{3} }{( { \frac{ - 3}{4}) }^{5} } \\ using \: formula > > \frac{ {a}^{m} }{ {a}^{n} } = {a}^{m - n} \\ = { (\frac{ - 3}{4} )}^{3 - 5} \\ = { (\frac{ - 3}{4}) }^{ - 2} \\ using \: formula > > {a}^{ - m} = \frac{1}{ {a}^{m} } \\ = \frac{1}{ { (\frac{ - 3}{4} )}^{2} } \\ = 1 \times ( { \frac{ - 4}{3}) }^{2} \\ = { (\frac{ - 4}{3} )}^{2} \\ = \frac{ {( - 4)}^{2} }{ {3}^{2} } \\ = \frac{ {4}^{2} }{ {3}^{2} } \\ = \frac{16}{9}$
