Question

simplify :
$\sqrt{8 {a }^{2} } 5 \times \sqrt[3]{4} {a}^{2} {b}^{2}$
​

Answer 1

$\sqrt{8 {a }^{2} } 5 \times \sqrt[3]{4} {a}^{2} {b}^{2} \\ \\ = \sqrt{ {2}^{2} {a}^{2} 2} \times \sqrt[3]{ {2}^{2} } {a}^{2} {b}^{2} \\ \\ = 2a \sqrt{2} \sqrt[3]{4} { a }^{2} {b}^{2} \\ \\ = 2 {a}^{3} {b}^{2} {2}^{ \frac{1}{2} } {2}^{ \frac{2}{3} } \\ \\ = 2^{ \frac{5}{6} } {a}^{3} {b}^{2}$
