create a Karnaugh map
xyz010011011111101000
Let’s select on the Karnaugh map rectangular areas of units of the largest area,
which are powers of two, and write out the conjunctions corresponding to them:
region 1
xyz010011011111101000
K1:y′
region 2
xyz010011011111101000
K2:x′z
Combining them using the OR operation, we get
y′+x′z
Answer: y′+x′z
