Complement the Boolean expression A + B.C.D.E

Complement the Boolean expression A + B.C.D.E Correct Answer A’.(B’ + C’ + D’ + E’)

The steps to derive the solution are given below. Using DeMorgan’s law twice, we get = (A + B.C.D.E)’ = A’.(B.C.D.E)’ = A’.(B’ + C’ + D’ + E’)

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.
