2∛3-√2+6∛3-7√2

Answer 1

Lembrete:

๏ $a\sqrt[b]{c}+d\sqrt[b]{c}=\left(a+d\right)\sqrt[b]{c}$
๏ $a\sqrt[b]{c}-d\sqrt[b]{c}=\left(a-d\right)\sqrt[b]{c}$
--------------------------------------------------
$2\sqrt[3]{3}-\sqrt{2}+6\sqrt[3]{3}-7\sqrt{2}\\2\sqrt[3]{3}+6\sqrt[3]{3}-\sqrt{2}-7\sqrt{2}\\8\sqrt[3]{3}-8\sqrt{2}\\\boxed{\bold{8\cdot \left(\sqrt[3]{3}-\sqrt{2}\right)}}$
