A'.B'.C'

(A+B+C)'

A+B+C'

A' + B' + C'​

Answer 1

Answer:

[a+b+c]'

Explanation

option b

Answer 2

The correct answer is (A' + B' + C')
Option (b) is correct.

• DeMorgan was a famous mathematician.
• He invented two most important theorems of boolean algebra.
• Used for verification of the NOR and negative AND gate and the negative OR and NAND gate.
• In this question the first theorem given by DeMorgan is used.
• The first theorem of DeMorgan says " the complement result of AND operation is equal to the OR operation of the complement of that variable."
• If we perform AND operation on two input variables followed by NOT operation, the result will be same as when we will perform OR operation on the complement of the variables.
