Commutative law states that:
- (a)$A \cdot (A + B) = A$
- (b)$(A \cdot B) \cdot C = A \cdot (B \cdot C)$
- (c)$A + (B + C) = (A + B) + C$
- (d)$(A + B) = (B + A)$
Answer
Answer
AICorrect option: (d)
Answer: (d) (A+B) = (B+A)
The Commutative law states that changing the order of operands does not change the result: A+B = B+A (and similarly A.B = B.A).
