Answer 3

to begin with, you would want to simplify the numbers in radicals.
rad(56) -> 6rad(14)
rad(24) -> 2rad(6)
rad(126) -> 3rad(14)
rad(54) -> 3rad(6)

3*6rad(14)-7*2rad(6)-3rad(14)+4*3rad(6)

Answer 4

18rad(14)-14rad(6)-3rad(14)+12rad(6)

Answer 5

and you can think rad(14) and rad(6) as variables (x,y)
So, the answer would be 3rad(14)-2rad(6)

Answer 6

the third one. and my bad, it's 6, not 18.

Answer 7
