Which of the following pairs of Boolean arithmetic laws cannot be used together? |
|||||||
Answer Values | |||||||
Identity and De Morgan’s theorem |
|||||||
Complementary and commutative |
|||||||
All the laws and rules can be used together |
As we all know .. de Morgan’s Theorem states that..... & .
Identity Law states that...A . 1 = A & A + 0 = A .
Complement law proves..A + = 1 & A . =0
Commutative law states that A+B = B+A & A.B = B.A
By analaysing the laws..we can understand that..de Morgan’s Theorem and identity laws cant be applied together because..when we apply de Morgan’s Theorem on identity laws..it will directly changes to de Morgan’s Theorem itself.
ie for eg. we apply them together... =..we get .that is de Morgan’s Theorem.
At the other side..we can use commutative and complimentary laws together.
THANKYOU..SIR/MADAM..hope this helped you..
