Question

What is the answer of
$3\sqrt[]{216}$

Answer 1

$if \: it \: is \: 3 \times \sqrt{216} \\ 3 \sqrt{216} = 3 \sqrt{2 \times 2 \times 2 \times 3\times 3 \times 3} \\ = 3 \times 6 \sqrt{6} = 18 \times \sqrt{6} =18 \times 2.44948974=44.0908153\\ \\ if \: it \: is \: \sqrt[3]{216} \\ \sqrt[3]{216} = \sqrt[3]{ {2}^{3} \times {3}^{3} } = 2 \times 3 = 6$
