Answer 1

Step-by-step explanation:

$\bold{x = {( \frac{3}{4}) }^{ - 2} \div {( \frac{3}{5} )}^{ - 3} } \\ = \frac{1}{ {( \frac{3}{4} )}^{2} } \div \frac{1}{ {( \frac{3}{5} )}^{ 3} } \\ = \frac{1}{ \frac{9}{16} } \div \frac{1}{ \frac{27}{125} } \\ = \frac{16}{9} \div \frac{125}{27} \\ = \frac{16}{9} \times \frac{27}{125} \\ = \frac{48}{125} \\ we \: find \: us \\ {x}^{ - 2} = {( \frac{48}{125}) }^{ - 2} \\ = { (\frac{125}{48}) }^{2} = \frac{15625}{2304}$

$\bold{\frac{15625}{2304} }$
