    Hello! i have a function that i need to simplify to add to a bigger question on my homework.

    the function i have is

    F= A'D + BC'D + AB'D'

    so far i have

    D(A' + BC') + AB'D' (which i simplified this way but im not sure is correct)

    = D(A' + BC') + D'(AB')
    = (D+D')(A' + BC')(AB')
    = (A' + BC')(AB')

    im not sure if it would be (A' +BC') + (AB') or the way i have it. anything helps!

    thanks!

    This series of equations is seriously wrong. You can't go from
    D(A' + BC') + D'(AB') to (D+D')(A' + BC')(AB').

    I suggest you do a revision on Boolean algebra rules.

    Must you simplify the expression through Boolean identities or can you use a Karnaugh map?

    If you got it from a K-map and you extracted it correctly from it, then there isn't much simplification that can improve the function's length.

    can we have a look at your output (F) so we can check if you did the k-map correctly..

    if you are 100% sure that your equation is correct, that one was already in simplified state.
