Question

simplify the expression y=AB'D+AB'D'Y=AB'D+AB'D'​

Answer 1

Answer:

Explanation:

From your last line, as you "prematurely grouped" the A′BC term into A′B, the absorption law can "recreate" an A′BC out of A′B:

p=A′B+C(A′B′+AB′+AB)=(A′B+A′BC)+C(A′B′+AB′+AB)=A′B+C(A′B+A′B′+AB′+AB)=A′B+C(A′+A)(B′+B)=A′B+C
