1. Is that a cubed in the 2nd expression? If so,
Sqrt (8a^3b) = 2asqrt(2ab), so we get
2sqrt(2ab) + 2asqrt(2ab). This cannot be simplified unless there is an a after the 2 is the first part.
2. Mult. both sides by sqrt 3. Then you get sqrt(24)/2*3 = 2sqrt6/6= sqrt6/3
3. Mult both sides by sqrt 5. Then you get
(2sqrt5+sqrt 75)/5 = (2sqrt5+5sqrt3)/5
