Answer 1

1)
$frac{(sqrt{5}-sqrt{13})^2}{9-sqrt{65}}=frac{5-2sqrt{13*5}+13}{9-sqrt{65}}=frac{18-2sqrt{65}}{9-sqrt{65}}=frac{2(9-sqrt{65})}{9-sqrt{65}}=2$


2)
$frac{(sqrt{38}-5sqrt{2})^2}{22-5sqrt{19}}=frac{38+50-10sqrt{2*19*2}}{22-5sqrt{19}}=frac{88-20sqrt{19}}{22-5sqrt{19}}=frac{4(22-5sqrt{19})}{22-5sqrt{19}}=4$
