Question

Me ajudem nessas questões de matemática, please

Answer 1

$7\sqrt[3]{2} - 2\sqrt[3]{2} - 5 \sqrt[3]{2} = \\ \\7 \sqrt[3]{2} - 7 \sqrt[3]{2} = 0$

$5 \sqrt{3} - 8\sqrt{3} - 4\sqrt{3} + 8\sqrt{3} + 2 = \\ \\ \sqrt{3} + 2$

$8 \sqrt[5]{7} - 12\sqrt[5]{7} + \sqrt[4]{6} - 10 \sqrt[4]{6} = \\ \\ - 4 \sqrt[5]{7} - 9 \sqrt[4]{6}$
