Do this question 6.7.8.9 plzz solve huryy up

Dear Student,

$$\begin{gathered} 7) i) \sqrt[3]{1.331} \\ = \sqrt[3]{\frac{1331}{1000}} \\ = {\left(\frac{{11}^3}{{10}^3}\right)}^{\frac{1}{3}} \\ = \frac{{11}^{3\times {\displaystyle \frac{1}{3}}}}{{10}^{3\times {\displaystyle \frac{1}{3}}}} \\ = \frac{11}{10} \\ ii) \sqrt[3]{0.003375} \\ = \sqrt[3]{\frac{3375}{1000000}} \\ = {\left(\frac{{15}^3}{{100}^3}\right)}^{\frac{1}{3}} \\ = \frac{{15}^{3\times {\displaystyle \frac{1}{3}}}}{{100}^{3\times {\displaystyle \frac{1}{3}}}} \\ = \frac{15}{100} \\ = 0.15 \end{gathered}$$
