#### Answer

The missing expressions are:
$8$;
$5$;
$2\sqrt[3]{5}$

#### Work Step by Step

RECALL:
$\sqrt[3]{ab} = \sqrt[3]{a} \cdot \sqrt[3]{b}$
Use the rule above to obtain:
$=\sqrt[3]{\underline{8}} \cdot \sqrt[3]{\underline{5}}
\\=\sqrt[3]{2^3} \cdot \sqrt[3]{5}$
Use the rule $\sqrt[3]{a^3}=a$ to obtain:
$=2 \cdot \sqrt[3]{5}
\\=2\sqrt[3]{5}$
