#### Answer

$2\sqrt{2}$

#### Work Step by Step

RECALL:
The quotient rule:
$\dfrac{\sqrt[n]{a}}{\sqrt[n]{b}}=\sqrt[n]{\dfrac{a}{b}}$
where
$\sqrt[n]{a}$ and $\sqrt[n]{b}$ are real numbers and $b\ne0$
Use the rule above to obtain:
$=\sqrt{\dfrac{40}{5}}
\\=\sqrt{8}$
Factor the radicand so that at least one factor is a perfect square then simplify to obtain:
$=\sqrt{4(2)}
\\=\sqrt{2^2(2)}
\\=2\sqrt{2}$
