Question

Efetue as multiplicações e divisões:
$12. \sqrt[4]{25} : 2. \sqrt[4]{5} \\ 10. \sqrt{8} : 2. \sqrt{2}$

Answer 1

$\dfrac{12. \sqrt[4]{25}}{2. \sqrt[4]{5}} \\ \\ \\ \dfrac{12. \sqrt[4]{5^2}}{2. \sqrt[4]{5}} \\ \\ \\ \dfrac{12. \sqrt{5} }{2. \sqrt[4]{5}} \\ \\ \\ => \dfrac{6.\sqrt{5} }{\sqrt[4]{5}}$

====

$\dfrac{10. \sqrt{8}}{2 \sqrt{2}} \\ \\ \\ \dfrac{10. \sqrt{2}^3}{2 \sqrt{2}} \\ \\ \\ \dfrac{20. \sqrt{2}}{2 \sqrt{2}} \\ \\ \\ \dfrac{20}{2} \ => 10$
