Problem 15E

Prove the second De Morgan law in Table l by showing that if A and B arc sets, then A ? B = A ? Ba) by showing each side is a subset of the other side.________________b) using a membership table.

Step-by-Step Solution:

Solution: Step 1 :We have to prove the second De Morgan law Mathematical form of second De Morgan law is consider If then by definition of compliment take ( definition of ( definition of .’. ( .’. Hence Hence the proof If A and B sets then consider shows .’. This shows if then A=BThen by De Morgan law put A=Bthen Hence this shows the De Morgan law is true in this set.
