I am preparing for an exam that I have on monday and the professor said that this would be on the exam for sure. I know the basic theorems of boolean algebra but I cannot quite simplify these 3. If someone could please explain how this would be done without using a truth table or k-map.
refer your notes. check out the identities you can apply to simplify these expressions. eg
Y=C(A+A'B')=>C(A+B') using(A+A'B)=A+B
Use De Morgan's law
if you solve first 2 you can do this one.
Here you can refer the basic rules.
