Answer 1

Пошаговое объяснение:

$( \frac{3}{4} ) {}^{2} \times 32 - 0.8 = \frac{9}{16} \times 32 - 0.8 = 9 \times 2 - 0.8 = 18 - 0.8 = 17.2$

Answer 2

${( \frac{3}{4} )}^{2} \times 32 - 0.8 = ( \frac{3}{4} \times \frac{3}{4} ) \times 32 - 0.8 = \frac{9}{16} \times 32 - 0.8 = \frac{9}{16} \times \frac{32}{1} - 0.8 = \frac{288}{16} - 0.8 = 18 - 0.8 = \boldsymbol{17.2}$
