Simply the radical expression $$10\sqrt[3]{8}-5\sqrt[3]{27}  $$

Uniteasy Admin · Accepted Answer

$$ 10\sqrt[3]{8}$$ and $$ 5\sqrt[3]{27}$$ are not like radicals as they have different radicands 8 and 27. However, their radicands are perfect cube numbers.
So we can take out the perfect cube numbers inside the radical symbol first.
$$ 10\sqrt[3]{8}-5\sqrt[3]{27} = 10	imes 2-5	imes 3 = 5 $$
