Answer
$3\sqrt[3]{5}$
Work Step by Step
Simplify each radical, when needed, to have:
$=2\sqrt[3]{5}-4\sqrt[3]{8(5)} + 3\sqrt[3]{27(5)}
\\= 2\sqrt[3]{5} -4\cdot2\sqrt[3]{5} + 3\cdot3\sqrt[3]{5}
\\= 2\sqrt[3]{5} -8\sqrt[3]{5} + 9\sqrt[3]{5}$
Combine like terms to have:
$=(2-8+9)\sqrt[3]{5}
\\=3\sqrt[3]{5}$
