Question

e essa é a ultima me ajudem :/

Answer 1

$\frac{2}{\sqrt5-\sqrt3}-\frac{2}{ \sqrt[3]{2}}\\\frac{2*(\sqrt5+\sqrt3)}{(\sqrt5-\sqrt3)(\sqrt5+\sqrt3)}-\frac{2*\sqrt[3]{2}}{\sqrt[3]{2}*\sqrt[3]{2}}=>\frac{2\sqrt5+2\sqrt3}{\sqrt{25}+\sqrt{15}-\sqrt{15}-\sqrt9}-\frac{2\sqrt[3]{2}}{2}=>\frac{2\sqrt5+2\sqrt3}{\sqrt{25}-\sqrt9}-\frac{2\sqrt[3]{2}}{2}=>\\\\\frac{2\sqrt5+2\sqrt3}{2}-\frac{2\sqrt[3]{2}}{2}=>\ \boxed{\boxed{\boxed{\sqrt5+\sqrt3-\sqrt[3]{2}}}}$
