I started with a'bc'+a'b'c+a'bc+abc and simplified it down to a'b+bc+a'b'c and know this is correct because i made truth tables but does anyone see any way to simplify the second expression even more? Im stuck.
I used a Karnaugh Map to get a'b + a'c + bc, which is the same as samzar. Combine the second and third term of the original expression to reduce the final term to a'c.
