Using Boolean algebra, the complete simplification of Z = AB + ...

[jc611]

Using Boolean algebra, the complete simplification of Z = AB + A(B + C) + B(B + C) gives us:
 
  A) Z = AB + AC + B B) Z = B - AC
  C) Z = AB = AC = BC D) Z = AB + AC + B + BC

Question 2

In a 1-of-10 BCD-to-decimal decoder:

  B) output line four will be activated when the input code is 01012.
  C) only one output line is activated at any one time.
  D) output lines 0-9 will be activated with any valid input BCD code.
