Answer 1

$( \frac{2}{3} ) {}^{ - 2} + (1 + \frac{2}{3} \times (\frac{1}{3} ) {}^{ - 3} ) \\ \\ (\frac{3}{2} ) {}^{2} + (1 + \frac{2}{3} \times ( 3) {}^{3} ) \\ \\ \frac{9}{4} + (1 + \frac{2 \times 3 {}^{3} }{3} ) \\ \\ \frac{9}{4} + (1 + 2 \times 3 {}^{2} ) \\ \\ \frac{9}{4} + (19) \\ \\ \frac{9}{4} + \frac{19}{1} \\ \\ \frac{9}{4} + \frac{76}{4} = \frac{85}{4} = 21.25$
