having trouble solving 2.7e from "Digital design & computer architecture" by Harris.

Sketch the combinational circuit from the Boolean equation.
Y = !(ABCD)+!(AB)CD+!(AC)BD+!(AD)BC+!(BC)AD+!(BD)AC+!(CD)AB+ABCD

WHERE !(AB)CD = notA AND notB AND C AND D.
thanks in advance.

You need to look at the notation a bit more closely. I haven't looked at that text, by a rather doubt !(AB)CD means what you claim. If that is what the author means, then you should find a different text (possibly at a different school). Consider this: How would you write (not (A AND B)) AND C AND D.
