Choose the correct option.
The proposition (a <=> b) is represented by:
The proposition $(a <=> b)$ is represented by:
- (a)$a'b' + ab$
- (b)$(a' + b') \cdot (a + b)$
- (c)$(a + b)'$
- (d)$(a \cdot b)'$
Answer
Answer
Correct option: (a)
Answer: (a) $a'b' + ab$
The biconditional a <=> b is true when both are equal: $ab + a'b'$ (XNOR).
