Question

Answer 1

22-
$3ab \sqrt[3]{ - 4 \times a}$
23-
${a}^{2} bc \sqrt[4]{ {b}^{2} {c}^{3} }$

Answer 2

$\sqrt[3]{ - 108 {a}^{4} {b}^{3} } = {( - 3b)}^{ \frac{3}{3} } {(2)}^{ \frac{2}{3} } {a}^{ \frac{4}{3} } = - 3b {( \sqrt{2}a) }^{ \frac{4}{3} } \\ \sqrt[4]{ {a}^{8} {b}^{6} {c}^{7} } = {( {a}^{8} {b}^{6} {c}^{7}) }^{ \frac{1}{4} } = {a}^{2} bc {b}^{ \frac{1}{2} } {c }^{ \frac{3}{4} }$
