Hi guys I was wondering if anyone could take a look at 2 expressions I have that I can't seem to simplify. Im basically one step away from the answer at both junctures but I can't logically apply a law that I know how to use to get the answer.
The first equation that I've pretty much solved has boiled down to this:
1.) A!B! + B!C + A! + B! + C! (Where ! means not. E.g A! = A not)
Final answer suppose to be A! + B! + C!
and secondly
2.) Q! + R! + S! + R!S + QR!R!
Final Answer suppose to be Q! + R! + S!
I cant seem to figure out what to do next. Im not aware of any law that can be applied here...though I do notice in both expressions B! and R! may have something to do with it respectively?
Thanks!
