Simplify the Boolean expression (A.B)’.

Simplify the Boolean expression (A.B)’. Correct Answer A’ + B’

The answer to the above question can be verified using the following truth table. A A’ B B’ A.B (A.B)’ A’+B’ 0 1 0 1 0 1 1 0 1 1 0 0 1 1 1 0 0 1 0 1 1 1 0 1 0 1 0 0 From the above table it can be verified that (A.B)’ = A’ + B’. Thus, DeMorgan’s law is verified.

You are given a boolean expression which consists of operators &, | and ∧ (AND, OR and XOR) and symbols T or F (true or false). You have to find the number of ways in which the symbols can be parenthesized so that the expression evaluates to true. This is the boolean parenthesization problem.
