I would love to help with your homework (especially since this is a really simple equation), but seeing as I assigned that problem, it would not be proper for me to help you and not the other students P.S. See me after class tomorrow to discuss not doing your own work

Think about the relation between the two expressions P.Q.R and P.R. If P.R is true, does it really matter what Q is?

If this is the digital logic class problem than the solution might look like this:

Assuming that it is Z = (P and Q and R) or (P and Q):

Let PR = X, let Q = Y then you can use the following simplifiction theorem: X + XY = X,

which will reduce the right hand side of the original expression to P*R.

So, I am guessing that you will get that Z = P*R.

It's not like asking for help is the same thing as asking for an answer. Though obviously this forum is the wrong place for it, asking for help isn't "not doing your own work"
