Answer 1

$10 {}^{3} - 5 {}^{2} \div 8 \times ( \frac{2}{3} ) {}^{5} \times 81 \\ \\ 1000 - 5 {}^{2} \div 8 \times ( \frac{2}{3} ) {}^{5} \times 81 \\ \\ 1000 - \frac{5 {}^{2} }{8} \times ( \frac{2}{3} ) {}^{5} \times 81 \\ \\ 1000 - \frac{5 {}^{2} }{8} \times \frac{32}{243} \times 81 \\ \\ 1000 - 5 {}^{2} \times \frac{4}{243} \times 81 \\ \\ 1000 - 5 {}^{2} \times \frac{4}{3} \\ \\ 1000 - 25 \times \frac{4}{3} \\ \\ 1000 - \frac{100}{3} \\ \\ 966.6$
