यदि \(A=\varnothing\) और \(B={x \in \mathbb{Z}:x^2=0}\), तो कौन सा कथन सही है?

If \(A=\varnothing\) and \(B={x \in \mathbb{Z}:x^2=0}\), which statement is correct?

Explanation opens after your attempt
Correct Answer

B. \(A\neq B\) क्योंकि \(B=\{0\}\)\(A\neq B\) because \(B=\{0\}\)

Step 1

Concept

The integer solution of \(x^2=0\) is (x=0).

Step 2

Why this answer is correct

So \(B=\{0\}\), which is a singleton set.

Step 3

Exam Tip

\(\varnothing\) and ({0}) are not equal. चरण 1: \(x^2=0\) का पूर्णांक हल (x=0) है। चरण 2: इसलिए \(B=\{0\}\), जो एकांक समुच्चय है। चरण 3: \(\varnothing\) और ({0}) समान नहीं होते।
