Question

please answer this question in detail.......​

Answer 1

$3 \sqrt[3]{40} - 4 \sqrt[3]{320} - \sqrt[3]{5}$

$3 \sqrt[3]{2 \times 2 \times 2 \times 5} - 4 \sqrt[3]{4 \times 4 \times 4 \times 5} - \sqrt[3]{5}$

$3 \times 2 \sqrt[3]{5} - 4 \times 4 \sqrt[3]{5} - \sqrt[3]{5}$

$6 \sqrt[3]{5} - 16 \sqrt[3]{5} - \sqrt[3]{5}$

$- 11 \sqrt[3]{5}$
