According to De Morgan’s law will be equal to:
According to De Morgan’s law $(a + b + c')'$ will be equal to:
- (a)$a' + b' + c'$
- (b)$a' + b' + c$
- (c)$a' \cdot b' \cdot c'$
- (d)$a' \cdot b' \cdot c$
Answer
Answer
AICorrect option: (d)
Answer: (d) $a' \cdot b' \cdot c$
By De Morgan's law the complement of a sum is the product of the complements: $(a + b + c')' = a' \cdot b' \cdot (c')' = a' \cdot b' \cdot c$.
