यदि \(A\cup B=U\), तो (\(A'\cap B'\)) क्या होगा?

If \(A\cup B=U\), what is \(A'\cap B'\)?

Explanation opens after your attempt
Correct Answer

C. \(\varnothing\)

Step 1

Concept

By De Morgan, (A'\cap B'=\(A\cup B\)'). Since \(A\cup B=U\), (\(A\cup B\)'=\varnothing).

Step 2

Why this answer is correct

The correct answer is C. \(\varnothing\). By De Morgan, (A'\cap B'=\(A\cup B\)'). Since \(A\cup B=U\), (\(A\cup B\)'=\varnothing).

Step 3

Exam Tip

डी मॉर्गन से (A'\cap B'=\(A\cup B\)')। चूंकि \(A\cup B=U\), इसलिए (\(A\cup B\)'=\varnothing)।
