Answer 1

6rad3-4rad6+10rad6-16-24rad2=6rad3+6rad6-4rad2-24rad2=6rad3+6rad6-28rad2

Answer 2

$2\sqrt{3}(3- \sqrt{8}+ 5\sqrt{2}) - 16 + 24 \sqrt{2}= \\ = ( 6\sqrt{3} - 2 \sqrt{24} + 10 \sqrt{6} ) - 16 +24 \sqrt{2}= \\ =(6 \sqrt{3} - 4 \sqrt{6} + 10 \sqrt{6})- 16 +24 \sqrt{2} = \\ = (6 \sqrt{3} + 8 \sqrt{6}) - 16 +24 \sqrt{2}$
