Answer 1

Answer:

$\sqrt[3]{ \frac{0.027}{0.008}} \div \sqrt{ \frac{0.09}{0.04}} - 1 \\ = \sqrt[3]{ \frac{ \frac{27}{1000} }{ \frac{8}{1000}}} \div\sqrt{ \frac{ \frac{9}{100}}{ \frac{4}{100}}} - 1 \\ = \sqrt[3]{ \frac{ {3}^{3} }{ {2}^{3}}} \div \sqrt{ \frac{ {3}^{2} }{ {2}^{2}}} - 1 \\ = \frac{3}{2} \div \frac{3}{2} - 1 \\ = \frac{3}{2} \times \frac{2}{3} - 1 \\ = - 1$
