Math Problem Statement

Use Boolean algebra to reduce the equation 𝐹(𝑥,𝑦,𝑧) = (𝑥′ + 𝑦′ + 𝑥′𝑦′ + 𝑥𝑦)(𝑥′ + 𝑦𝑧)

Solution

Let's reduce the Boolean function F(x,y,z)=(x+y+xy+xy)(x+yz)F(x, y, z) = (x' + y' + x'y' + xy)(x' + yz) using Boolean algebra rules step by step.

Step 1: Simplify the first part

The expression x+y+xy+xyx' + y' + x'y' + xy can be simplified by noticing that xyx'y' is redundant because:

x+y+xy=x+yx' + y' + x'y' = x' + y'

This follows from the absorption law, which states a+ab=aa + ab = a.

Thus, the expression becomes: x+y+xyx' + y' + xy

Step 2: The simplified function

Now the function becomes:

F(x,y,z)=(x+y+xy)(x+yz)F(x, y, z) = (x' + y' + xy)(x' + yz)

Step 3: Distribute the terms

Next, we will distribute the terms of the two factors: (x+y+xy)(x+yz)=x(x+yz)+y(x+yz)+xy(x+yz)(x' + y' + xy)(x' + yz) = x'(x' + yz) + y'(x' + yz) + xy(x' + yz)

This results in: =xx+xyz+yx+yyz+xyx+xyyz= x' \cdot x' + x' \cdot yz + y' \cdot x' + y' \cdot yz + xy \cdot x' + xy \cdot yz

Step 4: Simplify each term

  • xx=xx' \cdot x' = x' (idempotent law: aa=aa \cdot a = a)
  • xyz=xyzx' \cdot yz = x'yz
  • yx=xyy' \cdot x' = x'y'
  • yyz=yyz=0y' \cdot yz = y'yz = 0 (since yy=0y' \cdot y = 0)
  • xyx=0xy \cdot x' = 0 (since xx=0x \cdot x' = 0)
  • xyyz=xyzxy \cdot yz = xyz

Thus, we now have: F(x,y,z)=x+xyz+xy+xyzF(x, y, z) = x' + x'yz + x'y' + xyz

Step 5: Simplify the final expression

Group the terms involving xx': F(x,y,z)=x(1+yz+y)+xyzF(x, y, z) = x'(1 + yz + y') + xyz Since 1+yz=11 + yz = 1 (anything OR'd with 1 is 1), we simplify to: F(x,y,z)=x+xyzF(x, y, z) = x' + xyz

Thus, the reduced Boolean expression is: F(x,y,z)=x+xyz\boxed{F(x, y, z) = x' + xyz}

Final Answer:

The simplified Boolean function is F(x,y,z)=x+xyzF(x, y, z) = x' + xyz.
