Explanation of Solution

Simplification:

F(x, y, z) = x⋅y'⋅z + x⋅(y + z')' + x⋅y'⋅z'= x⋅y'⋅z + x⋅(y'⋅z) + x⋅y'⋅z' (by DeMorgan's law)= x⋅y'⋅z + x⋅y'⋅z + x⋅y'⋅z' = x⋅y'⋅z + x⋅y'⋅z' (by Idempotent law)

= x⋅y'⋅(z + z') (by Idempotent law)= x⋅y'⋅(1) (by Inverse law)= x⋅y' (by Identity law)

Therefore, the simplified expression is “x⋅y'”.
