Even if someone would do one showing me how to do it would be great.

1) Pretend Root 11 is x. x+2x=3x i.e. 3root11
2) 7x-root7x -7
3) Same
4) root 144 is 12. root 40 is the same as 2root10 because 4 is a square number (Take it out using laws of indices). So 12-2root10-root10 simplify
5) Take 4 out of the root.
