Question

Find using karnaugh maps a minimal form for the boolean function. f (x, y, z) = xyz + xyz' + x'yz' + x'y'z'

Answer 1

What's the numbers?, You need one number.

Answer 2

Answer:

$f(x,y,z)=xy+yz'+x'z'$

Step-by-step explanation:

Check the squares corresponding to the four summands as in figure.  Observe that has three prime implicants (maximal basic rectangles), which are circled; these are $xy,yz'$ and $x'z'.$ All three are needed to cover.

Hence the minimal sum of $f(x,y,z)=xy+yz'+x'z'$
