What is (\(A\cup B'\)') equal to?

Explanation opens after your attempt
Correct Answer

A. \(A'\cap B\)

Step 1

Concept

By De Morgan's law, (\(A\cup B'\)'=A'\cap(B')'=A'\cap B). When taking complement, \(\cup\) changes to \(\cap\).

Step 2

Why this answer is correct

The correct answer is A. \(A'\cap B\). By De Morgan's law, (\(A\cup B'\)'=A'\cap(B')'=A'\cap B). When taking complement, \(\cup\) changes to \(\cap\).

Step 3

Exam Tip

डी मॉर्गन नियम से (\(A\cup B'\)'=A'\cap(B')'=A'\cap B)। पूरक लेते समय \(\cup\) बदलकर \(\cap\) होता है।
