Answer 2

Step-by-step explanation:

$[( \frac{4}{3})^{ - 2} - ( { \frac{3}{4} })^{ 2} ]^{2} \\ = ( \frac{ \frac{4}{3} }{ {1}^{2} } - \frac{ \frac{9}{16} }) ^{2} \\ = ( \frac{ \frac{4}{3} }{1} - \frac{ \frac{9}{16} )^{2} \\ = (\frac{4}{3} - \frac{3}{4} )^{2} \\ = ( \frac{16 - 9}{12} )^{2} \\ = {( \frac{7}{12} })^{2} \\ = \frac{49}{12} \\ \\Answer: \: \frac{49}{12}$
