3) Find the complement of the following expression. Then, simplify the complement as much as you can. (Only single variables may be complemented in your answer -- - (a+b)' is not acceptable part of answer format). (a + b) (b' + c) + d' (a'b + c) 4) Consider the following function with don't cares: g(x, y, z)= m (5, 6) +d (1,2,4) Determine if any of the following expressions can be used as a solution for g? Explain your answers. a) z' + xy'z b) x(y' + z') c) yz' + y'z 5) Draw the diagram of the following expressions using only NAND gates. Assume all inputs are available both uncomplemented and complemented. Do not simplify equations. a) F=a'bd' +c' d+bcd b) G=z (y' +x'w') + w' (xy' +zx')
