Hey does any one knows how to solve an expression as follows:

(a+b)' (a+b')

I am suppose to draw a circuit diagram for the original expression
Simplify the expression with Boolean algebra to a minimum number of gates
Draw a circuit diagram for the simplified expression.

Thsnks in advance.

To be honest, you can completely ignore any & all rules if you simply put every possible combination of 0 and 1 in for A and B, and record the results. . then you will come up with your solution. Since you only have two variables it isn't like you have many things to test, 2^2 = 4.

0,0
0,1
1,0
1,1

thanks much.
