Answer
$2\sqrt[3]{6}$
Work Step by Step
RECALL:
For any non-negative real numbers a and b,
$\sqrt[n]{a} \cdot \sqrt[n]{b} = \sqrt[n]{ab}$
Use the rule above to obtain:
$=\sqrt[3]{(12)(4)}
\\=\sqrt[3]{48}$
Factor the radicand (expression inside the radical sign) so that at least one factor is a cube, and then simplify to obtain:
$\\=\sqrt[3]{8(6)}
\\=\sqrt[3]{2^3(6)}
\\=2\sqrt[3]{6}$
