anyone mind checking it

1) 3$\sqrt[6]{3}$ - 2$\sqrt[6]{192}$ - 6$\sqrt[6]{320}$ = -3$\sqrt[6]{3}$ - 4$\sqrt{3}$ - 2$\sqrt{5}$ = $\sqrt[6]{3}$ + 2$\sqrt{5}$

2) $\sqrt[3]{320}$ - 4$\sqrt[3]{5}$ + 2$\sqrt[3]{135}$ + 2$\sqrt[3]{16}$ = -4$\sqrt{5}$ - 4$\sqrt[3]{5}$ + 6$\sqrt{5}$ + 4$\sqrt{2}$ =
6$\sqrt[3]{5}$ + 4$\sqrt{2}$

3)2$\sqrt[3]{6}$ - $\sqrt[6]{6}$ + 3$\sqrt[3]{6}$
- 3$\sqrt[6]{384}$ = 2$\sqrt[3]{6}$ - $\sqrt[6]{6}$ + 3$\sqrt[3]{6}$ - 6$\sqrt{6}$
