Question

Помогите пожалуйста!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answer 1

$(3-2\sqrt{2} )\sqrt{17+12\sqrt{2}} +(\sqrt{3}-2)\sqrt{7+4\sqrt{3}}=$$=(3-2\sqrt{2} )\sqrt{(3+2\sqrt{2})^2}+(\sqrt{3}-2)\sqrt{(\sqrt{3}+2)^2}=$$=(3-2\sqrt{2} )|3+2\sqrt{2}|+(\sqrt{3}-2)|\sqrt{3}+2|= (3-2\sqrt{2} )(3+2\sqrt{2})+(\sqrt{3}-2)(\sqrt{3}+2)=$$=3^2-(2\sqrt{2} )^2+(\sqrt{3})^2-2^2=9-8+3-4=0$
