    I've gotten this far and don't know what to do....
    I am trying to simplify this further.

    U=X(not) Y Z+X Y(not) Z+ X Y Z(not)+ X(not) Y(not) Z(not)

    You can simplify further if you use an XOR, otherwise that's as simple as it gets as far as I can tell.

    Sorry, im having trouble understanding these concepts
    How Would I use the Ex-or function for this??.... would it then simplify to X and or Z? hmm..

    Do you know the truth-table for xor? xor has nothing to do with your X variable.
    XOR:
    A B | Q
    0 0 | 0
    0 1 | 1
    1 0 | 1
    1 1 | 0

    Are you using a k-map to help you simplify? If you draw out the k-map, you'll notice a checkerboard pattern, which is indicative of an xor function.

    This can be simplified by merely taking common factors: Z(NOT) and Z are ones that jump out immediately.

    Again check the Boolean Algebra page here at AAC: http://www.allaboutcircuits.com/vol_4/chpt_7/index.html
