    for the first one, dealing with square/cube roots is hard. so if you cube one side of the equation it will make it easier. but once you cube one side, you have to cube the other side as well. and after that you just solve for x. hope that helps

    so lets look at one side seperately first. cubing, cuberoot (3x-1) is the same as saying cuberoot(3x-1) times cuberoot (3x-1) times cuberoot (3x-1), right? so we get cuberoot (3x-1) (3x-1) (3x-1) [we just wrote them inside one cuberoot] so now we have 3 (3x-1)'s inside a cuberoot? so that's the same as cuberoot(3x-1) ^3 so basically you're cubing and cuberooting the same thing. so they cancel. right? so it would just be (3x-1) now for the other side, we have 2. we also have to cube this now. so, 2x2x2 = 8 now putting the two sides together, we have (3x-1) = 8 hope that made sense :)

    no problem. ok for this one it's the same type of question except theres a square root instead of a cube root. so give it a try.
