porfa ayudenme siii porfa vor 

Answer 1

$(\sqrt{\frac{5}{3} }*\sqrt{6})-(\sqrt{\frac{12}{5}}+\sqrt{5})=(\frac{\sqrt{5}}{\sqrt{3}}*\sqrt{6})-(\frac{\sqrt{12}}{\sqrt{5}}+\sqrt{5})=\\\\=\frac{\sqrt{30}}{\sqrt{3}}-(\frac{\sqrt{12}}{\sqrt{5}}+\sqrt{5})=\sqrt{10}-(\frac{\sqrt{12}}{\sqrt{5}}*\frac{\sqrt{5}}{\sqrt{5}}+\sqrt{5} )=\\\\=\sqrt{10}-\frac{\sqrt{60}}{5}-\sqrt{5}=\frac{5\sqrt{10}-\sqrt{60}-5\sqrt{5}}{5}=\\\\=\frac{5\sqrt{10} }{5}-\frac{\sqrt{60}}{5}-\frac{5 \sqrt{5}}{5}= \sqrt{10}-\frac{ \sqrt{2^{2}*3*5} }{5}-\sqrt{5}=\\\\= \sqrt{10}- \frac{2}{5}\sqrt{15}-\sqrt{5}$
