Question

Use DeMorgan’s Laws to find the complement of xy` + x`y

Answer 1

\[\large xy' + x'y\]

like that ?

Answer 2

I think, that it is:
\[\large \left( {x' \cdot y} \right) \cdot \left( {x \cdot y'} \right)\]

Answer 3

@rational: Yes, like that.

Answer 4

I'm very sorry, my previous answer is wrong @keepo

Answer 5

\[\begin{align} \overline{xy' + x'y} &= \overline{xy'} \cdot \overline{x'y}\\~\\&=(x'+y)\cdot (x+y')\\~\\&=xy + x'y'\end{align}\]

Answer 6

Thanks! what about b) on that screenshot

Answer 7

Is "complement" just simplifying out the equation?

Answer 8

yes

Answer 9

alright...let me give it a shot. learned this a few months ago, gonna give it a go.

Answer 10

let me create a new thread so I can give you a medal because I already gave a medal to rational
