Can anyone help with Demorgans and simpification please? The " ' " represent the nots. I wish I could write it on here better but this is the only way I see to. Some of the variables have more than one bar over them. I have tried several attempts at this and this is what I have.

(C'+D')A''C'''D''(A''C'+D'')=X one bar is over the entire equation

C'+D' + A''C'''D'' + A''C'+D''

C'+D' + AC'D + (A''+C')(D'')

C'+D' + AC'D + AD + C'D

C'+D' + C'D(A+1) + AD

C'+D' + C'D + AD

C'D' + C'D + AD

C'(D'+D) + AD

C' +AD

Thanks
