From the expressions given below find the expressions that are in agreement with absorption law.

(a) A. (A+B)

(b) B’.(A+ B’)

(c) A+ (A’. A)

(d) C’ .(C+A)

(e) B.(B+B)

(f) B+(B+B)

(g) C’.(C’+D)

 

Answer:

Absorption law states that 

  • A.(A+B) = A
  • A+(A.B) = A

Checking the options:

  • (a) A. (A+B) - Satisfies absorption law
  • (b) B’.(A+ B’) - Satisfies absorption law  
  • (c) A+ (A’. A) - Satisfies absorption law
  • (d) C’ .(C+A) - Does not satisfy absorption law   
  • (e) B.(B+B) - Does not satisfy absorption law     
  • (f) B+(B+B) - Does not satisfy absorption law     
  • (g) C’.(C’+D) - Satisfies absorption law

Therefore, the options that are in agreement with absorption law are a, b, c, g.
