HW7.3 (continuation) 2-4 +Given that A-B = 0 and A + B 1 , use algebraic manipulation to prove that (A + C) . (A+B),(B+C)=B-C Hint 1 Note that by (5) A = B , which is equivalent with B A II Multiply out 2-8 Using DeMorgan's theorem, express the function Use De Morgan's (10) for (a) =(X (a) with only OR and complement operations (b) with only AND and complement operations. for (b): 2-9 Complement the following expressions: a) AB+AB e_perform a the_rest still_as HW 8.0 (if not done yet (AB.AB) (A B) (AB) (a- B)(A.B)-AB.AB
