Transcript text: Use De Morgan's laws to determine whether the two statements are equivalent.
\[
\sim(\sim y \vee z) \rightarrow x,(y \wedge \sim z) \rightarrow x
\]
Choose the correct answer below.
The two statements are not equivalent.
The two statements are equivalent.
Solution
Solution Steps
Step 1: Apply De Morgan's Laws to the First Statement
Start with the first statement:
\[
\sim(\sim y \vee z) \rightarrow x
\]
Apply De Morgan's laws to \(\sim(\sim y \vee z)\):
\[
\sim(\sim y \vee z) \equiv y \wedge \sim z
\]
So, the first statement becomes:
\[
(y \wedge \sim z) \rightarrow x
\]
Step 2: Compare the Transformed First Statement with the Second Statement
The second statement is:
\[
(y \wedge \sim z) \rightarrow x
\]
After applying De Morgan's laws, the first statement is identical to the second statement.
Step 3: Conclude Equivalence
Since both statements simplify to the same logical expression, they are equivalent.
The correct answer is: The two statements are equivalent.
