ok there are a few that im have a lot of difficulty with.... some help would be GREAT (:

1.) square root of (x + 6) - square root of (x-5) = 1

2.) square root of (2x -1) = square root of (x-1) + 1

3.) x^2/3 + x^1/3 - 2 = 0

4.) cube root of (3x-7) = cube root of (4-x)

5.) square root of (y) + fourth root of (y) = 6

i was thinking of using the "let u =" thing but im not sure if that would work...

6.) cube root of (x + 1) = sixth root of (4x + 9)

i know theres quite a few but help on any of them would be awesome <33
