Answer 1

Explicación paso a paso:

$\frac{5}{8} \times ( \frac{1}{4} ) ^{ - 1} + \frac{9}{5} \times \sqrt{ \frac{ {3}^{3} \times 3 }{9} } - \frac{7}{10} \\ \\ \frac{5}{8} \times 4 + \frac{9}{5} \times \sqrt{ \frac{27 \times 3}{9} } - \frac{7}{10} \\ \\ \frac{20}{8} + \frac{9}{5} \times \sqrt{ \frac{81}{9} } - \frac{7}{10} \\ \\ \frac{20}{8} + \frac{9}{5} \times \sqrt{9} - \frac{7}{10} \\ \\ \frac{20}{8} + \frac{9}{5} \times 3 - \frac{7}{10} \\ \\ \frac{20}{8} + \frac{27}{5} - \frac{7}{10} = \\ \\ \frac{100 + 216 - 28}{40} = \frac{288}{40} = \frac{36}{5}$
