Answer 1

     
$\sqrt{(4 \sqrt{3}-7)^{2}}+ \sqrt{(5 \sqrt{2}-7)^{2}}+2(1+ \sqrt{2})^{2}+ \sqrt{2}+(2+ \sqrt{2})^{2}= \\ = 7-4 \sqrt{3}+ 5 \sqrt{2}-7+2(1+2 \sqrt{2} +2)+ \sqrt{2}+ 4+4\sqrt{2}+2= \\ =7-4 \sqrt{3}+ 5 \sqrt{2}-7+6+4 \sqrt{2} + \sqrt{2}+ 4+4\sqrt{2}+2= \\ 7-7+6+4+2+5 \sqrt{2}+4 \sqrt{2} + \sqrt{2}+ 4\sqrt{2}-4 \sqrt{3}= \\ =12+14 \sqrt{2} -4 \sqrt{3}$
