Question

Rút gọn :

E=\(\frac{5\sqrt{5}+3\sqrt{3}}{\sqrt{3}+\sqrt{5}}\)

Answer 1

E=\(\frac{\left(\sqrt{5}\right)^3+\left(\sqrt{3}\right)^3}{\sqrt{5}+\sqrt{3}}=\frac{\left(\sqrt{5}+\sqrt{3}\right)\left(5-\sqrt{15}+3\right)}{\sqrt{5}+\sqrt{3}}\)=8-\(\sqrt{15}\)

Answer 2

\(\frac{5\sqrt{5}+3\sqrt{3}}{\sqrt{3}+\sqrt{5}}=8-\sqrt{15}\)nha  hoshi nguyen                    ^_^
