Answer 1

$1); ; frac{sqrt3-sqrt2}{sqrt[4]3+sqrt[4]2}=frac{(sqrt[4]3-sqrt[4]2)(sqrt[4]3+sqrt[4]2)}{sqrt[4]3+sqrt[4]2}=sqrt[4]3-sqrt[4]2\\2); ; frac{19}{sqrt[3]{100}-sqrt[3]{90}+sqrt[3]{81}}-sqrt[3]{10}-sqrt[3]{9}= \\=frac{19-(sqrt[3]{10}+sqrt[3]9)(sqrt[3]{100}-sqrt[3]{90}+sqrt[3]{81})}{(sqrt[3]{10})^2-sqrt[3]{10}cdot sqrt[3]9 +(sqrt[3]{9})^2} = frac{19-(10+9)}{(sqrt[3]{10})^2-sqrt[3]{10}cdot sqrt[3]9+(sqrt[3]{9})^2} =0$
