$=(3\sqrt{2} -5)*(\sqrt{2} +1)+\frac{2\sqrt{6} -10\sqrt{3} }{\sqrt{3} }=6+3\sqrt{2} -5\sqrt{2} -5+\frac{2\sqrt{6}-10\sqrt{3})\sqrt{3}   }{3}=1-2\sqrt{2} +\frac{2\sqrt{18}-30 }{3}=1-2\sqrt{2} +\frac{3(2\sqrt{2}-10) }{3}=1-2\sqrt{2} +2\sqrt{2} -10=-9$

201

$=20\sqrt{6} -(2\sqrt{2} +5\sqrt{3} )^{2} = 20\sqrt{6} -(8+20\sqrt{6} +75)=20\sqrt{6} -(83+20\sqrt{6} )=20\sqrt{6} -83-20\sqrt{6} =-83$
