Step-by-step explanation :-
1. Bring the common value.
2. Take same value common.
3. Reach to the required answers.
\begin{gathered} = 3 \sqrt[3]{40} - 4 \sqrt[3]{320} - \sqrt[3]{5} \\ \\ 3 \sqrt[3]{40} = 3 \sqrt[3]{8 \times 5} = 6 \sqrt[3]{5} \\ 4 \sqrt[3]{320} = 4 \sqrt[3]{8 \times 8 \times 5} = 16 \sqrt[3]{5} \\ \\ = 6 \sqrt[3]{5} - 16 \sqrt[3]{5} - \sqrt[3]{5} \\ \\ = \sqrt[ 3]{5} (6 - 16 - 1) \\ \\ = - 11 \sqrt[3]{5} \end{gathered}
