Answer 2

 

$\Rightarrow\ 3\sqrt[3]{40}-4\sqrt[3]{320}-\sqrt[3]{5} \\ \\ \Rightarrow\ 3\sqrt[3]{8 \times 5}-4\sqrt[3]{64 \times 5}-\sqrt[3]{5} \\ \\ \Rightarrow\ 3\sqrt[3]{2^3 \times 5}-4\sqrt[3]{4^3 \times 5}-\sqrt[3]{5} \\ \\ \Rightarrow\ 3 \times 2\sqrt[3]{5}-4 \times 4\sqrt[3]{5}-\sqrt[3]{5} \\ \\ \Rightarrow\ 6\sqrt[3]{5}-16\sqrt[3]{5}-\sqrt[3]{5} \\ \\ \Rightarrow\ (6-16-1)\sqrt[3]{5} \\ \\ \Rightarrow\ -11\sqrt[3]{5} \\ \\ \Rightarrow\ \sqrt[3]{-1331 \times 5} \\ \\ \Rightarrow\ \bold{\sqrt[3]{-6655}}$

Hence simplified!!!
