Final answer:
The expression (x'z' + x'z) + yz' simplifies to x' + yz' using the distributive and complement properties of Boolean algebra.
Step-by-step explanation:
To simplify the Boolean expression (x'z' + x'z) + yz', we will apply the distributive property and then the idempotence property of Boolean algebra.
First, let's apply the distributive property to x'z' + x'z, which is similar to the distributive property (A(B + C) = AB + AC) in normal algebra:
x'z' + x'z = x'(z' + z) = x' because z' + z is 1 due to the complement property.
Now, we can substitute x' back into the original expression:
(x'z' + x'z) + yz' becomes x' + yz'.
The expression x' + yz' is already in its simplest form according to Boolean algebra; therefore, the simplified expression is x' + yz'.
We have thus used the distributive property to simplify the first part of the expression, and then we recognized that the expression was already simplified.
