Question

1-√3=
  √3








3-√2=


√2








√2+√5=
 √5

Answer 1

$\boxed{\frac{1- \sqrt{3} }{ \sqrt{3} }.\frac{ \sqrt{3} }{ \sqrt{3} }=\frac{ \sqrt{3} -3}{3}}\\ \\ \\ \boxed{\frac{3- \sqrt{2} }{ \sqrt{2} }.\frac{ \sqrt{2} }{ \sqrt{2} }=\frac{3 \sqrt{2} -2}{2}}\\ \\ \\ \boxed{\frac{ \sqrt{2} + \sqrt{5} }{ \sqrt{5} }.\frac{ \sqrt{5} }{ \sqrt{5} }=\frac{\sqrt{10}+5}{5}}$
