Answer 1

$- \sqrt{25} \times \frac{ - 8}{10} \\ \\ - 5 \times \frac{ - 8}{10} \\ \\ - 5 \times ( - \frac{8}{10} ) \\ \\ 5 \times \frac{8}{10} \\ \\ \: \div \: \: 5 \ \\ \\ \frac{8}{2} \\ \\ \div \: 2 \\ \\ 4$

$\sqrt[3]{ \frac{8}{27} } - \sqrt{ \frac{64}{4} } \\ \\ \\ \frac{2}{3} - \sqrt{ \frac{64}{4} } \\ \\ \frac{2}{3} - \sqrt{16} \\ \\ \frac{2}{3} -4 \\ \\ - \frac{10}{3}$
