Question

solve the given questions with the help of truth table
X'Y' +X'Y =?
X'YZ'+XY'=?
X'Y'(Z+ YZ')+Z'=?
​

Answer 1

Answer:

In line 3, x' is taken as A and y as B…

So naturally, x becomes A'

Similarly in line 5, x' is taken as A and z' as B…

And again, x becomes A'

On the right hand side is a rule of conversion of A+A'B…
