Math Problem Statement
-
$X = \overline{A.\overline{B}} + \overline{A.(\overline{A}+C)}$
-
$X = \overline{(AB.\overline{C+D}).AB}$
Solution
Let's simplify both Boolean expressions step-by-step.
1.
Step 1: Apply De Morgan's Law
-
First, simplify each part separately.
-
For the term , use De Morgan's law:
-
Now for , apply De Morgan's law: Here, is simplified further using De Morgan's law: So the term becomes:
Step 2: Combine the terms
Now substitute these simplified forms back into the original expression:
Step 3: Simplify
We can combine from both terms: This is the simplest form of the Boolean expression.
Final simplified expression:
2. ( X = \overline{(AB.\overline{
