Answer 1

Ответ:

$( \frac{2}{3} ) {}^{2} \times ( - 9) {}^{2} - (0.5) {}^{3} = ( \frac{2}{3} ) {}^{2} \times 9 {}^{2} - ( \frac{1}{2} {}^{3} = ( \frac{2}{3} \times 9) {}^{2} - \frac{1}{8} = (2 \times 3) {}^{2} - \frac{1}{8} = 6 {}^{2} - \frac{1}{8} = 36 - \frac{1}{8} = \frac{287}{8} = 35 \frac{7}{8}$
