यदि \(A-B=A \cap B'\) है, तो ((A-B)') किसके बराबर होगा?
If \(A-B=A \cap B'\), what is ((A-B)') equal to?
Explanation opens after your attempt
Correct Answer
A. \(A' \cup B\)
Concept
((A-B)'=\(A \cap B'\)'=A' \cup (B')'). Therefore the answer is \(A' \cup B\).
Why this answer is correct
The correct answer is A. \(A' \cup B\). ((A-B)'=\(A \cap B'\)'=A' \cup (B')'). Therefore the answer is \(A' \cup B\).
Exam Tip
((A-B)'=\(A \cap B'\)'=A' \cup (B')') होता है। इसलिए उत्तर \(A' \cup B\) है।
