Answer 1

Resposta:

168=2*3*7*4=2*3*7*2² =2³*3*7

∛168 = ∛ (2³*3*7) =2∛21

Answer 2

$\sqrt[3]{168} = \\ \\ 168 |2 \\ 84 \: \: |2 \\ 42 \: \: |2 \\ 21 \: \: |21 \\ 1 \: \: \: \: \boxed{ {2}^{3} \times 21 } = \\ \\ \sqrt[3]{ {2}^{3} \times 21 } = \\ \sqrt[\diagup\!\!\!\! 3]{ {2}^{\diagup\!\!\!\! 3} } \sqrt[3]{21} = \\ \boxed{2 \sqrt[3]{21} }$
