(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

1.

Simplify the following problem using boolean algebra:

(p+q'r')(p'q'+r)

2.

Use algebra or karnaugh maps to simplify the following circuit:

(z+xy')+yx+xzy'

2. Relevant equations

Boolean algebra rules and demorgan's law

3. The attempt at a solution

1. (p+q'r')(p'q'+r)

=pq'p'+pr+q'r'p'q'+q'r'r

=0q'+pr+'q'r'p+0q

=pr+q'r'p'

=0r+q'r'

=00+q'

=q'

Not sure if correct

2.(z+xy')+yx+x(z+y')

=zxy'+yx+xzy'

=zxy'+1x+xz

=x(zy'+z)

=xz

Not sure about this one either
