Answer 1

5*√5*√5+√45*√5-2*√2*√2+√50*√2=

=25+15-4+10=46

Answer 2

$(5\sqrt{5}+\sqrt{45})*\sqrt{5}-(2\sqrt{2}-\sqrt{50})*\sqrt{2}=\\\\=(5\sqrt{5}+\sqrt{9*5})*\sqrt{5}-(2\sqrt{2}-\sqrt{25*2})*\sqrt{2}=\\\\=(5\sqrt{5}+3\sqrt{5})*\sqrt{5}-(2\sqrt{2}-5\sqrt{2})*\sqrt{2}=8\sqrt{5}*\sqrt{5}+3\sqrt{2}*\sqrt{2}=\\\\=8*5+3*2=40+6=46\\\\Otvet:\boxed{46}$
