Definition of Boolean Algebra:
Boolean algebra is a branch of mathematics dealing with variables that have two possible values: true (1) and false (0). It is commonly used in computer science, logic, and digital circuits. Boolean algebra uses three primary operations:
- AND (⋅): A ⋅ B is true only if both A and B are true.
- OR (+): A + B is true if either A or B is true.
- NOT ('): Negation inverts the value (true becomes false, and false becomes true).
Boolean algebra satisfies specific laws and properties:
- Commutative law: A + B = B + A, A ⋅ B = B ⋅ A
- Associative law: (A + B) + C = A + (B + C), (A ⋅ B) ⋅ C = A ⋅ (B ⋅ C)
- Distributive law: A ⋅ (B + C) = (A ⋅ B) + (A ⋅ C)
- Identity laws: A + 0 = A, A ⋅ 1 = A
- Idempotent laws: A + A = A, A ⋅ A = A
- Complement laws: A + A' = 1, A ⋅ A' = 0
Solutions:
(i) Prove:
Using the laws of Boolean algebra:
- Apply the Distributive Law: .
- From the Idempotent Law, , so .
- From the Absorption Law, .
Thus, .
(ii) Prove:
We need to show the equality of these terms using associativity and commutativity:
-
Start with :
- Using the Associative Law, .
-
For :
- By the Distributive Law, we can rewrite as combining terms and , since these terms are commutative.
Thus, .
