a ⊕ b = ________(a) (a+b)(a`+b`)(b) (a+b`)(c) b`(d) a` + b`This question was posed to me in an internship interview.Query is from Boolean Functions topic in chapter Boolean Algebra and Modeling Computations of Discrete Mathematics

Answer»

Correct choice is (a) (a+b)(a`+b`)

For EXPLANATION: a ⊕ b

= a`b + AB`

= a`b+aa` + bb` + ab` [As, a*a` = 0 and b*b` = 0]

= a`(a+b) + b`(a+b)

= (a+b)(a`+b`).
