Hi folks

I am doing an assignment that requires me construct 2 boolean equations and then simplify them.

I have come up with the equations but am stuck with the simplifying part.

My two equations are as follows:

1. cd + (c+d)(a'b') + a'b'c'd'

2. ab(c'd') + (a+b)(c'd')

I hope i have written this correctly.

Thanks

Have you been told what the metric is for "simple"? My guess is no, and so there really isn't any firmly correct answer. So let's do the best we can.

For you first one:

Q1) Do you see any common factors between the second and third terms?

Q2) What happens if you factor out that common factor? Hint, if something doesn't jump out at you, prepare a truth table for the factor involving the c's and d's.

For the second one:

Q3) Do the same thing. This one should be significantly easier.
