problem 1:

F(wxyz)= wx+xyz+x'yz+x'yz'+[wx+w' (x+z)]

i did this but i got stacked.

F(wxyz)= wx+xyz+x'yz+x'yz'+[wx+w' (x+z)]

= wx+xyz+x'y(z+z')+[wx+w' (x+z)]

=wx+xyz+x'y+(w'+x')wx.wz

=wx+xyz+x'y

can any1 tell me if i made a mistake? if its going to simplify more?

also i got this one:

problem 2: f(a,b,c)= a'b'c+a'bc'+ab'c+abc'+abc i did this:

=a'b'c+a'bc'+ab'c+ab(c'+c)

=a'b'c+a'bc'+ab'c+ab

=a'b'c+a'bc'+ac+a

=a'b'c+a'bc'+a

can any1 tell me if i made a mistake? if its going to simplify more?

tnx a lot for reading!
