Resposta:

41/16

Explicação passo-a-passo:

$( \frac{4}{3} ) {}^{ - 2} - ( \frac{1}{2}) {}^{ - 1} + ( \frac{2}{4}) {}^{ - 2} \\ ( \frac{3}{4}) {}^{2} - ( \frac{1}{2}) { }^{ - 1} + ( \frac{2}{4}) {}^{ - 2} \\ ( \frac{3}{4}) {}^{2} - 2 + ( \frac{2}{4}) {}^{ - 2} \\ ( \frac{3}{4}) {}^{2} - 2 + ( \frac{1}{2}) {}^{ - 2} \\ \frac{9}{16} - 2 + ( \frac{1}{2}) {}^{ - 2} \\ \frac{9}{16} - 2 + 2 {}^{2} \\ \frac{9}{16} - 2 + 4 \\ \frac{9}{16} + 2 = \frac{41}{16}$
