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

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

Explanation opens after your attempt
Correct Answer

B. \(A=\{0\}\) और \(A\ne B\)\(A=\{0\}\) and \(A\ne B\)

Step 1

Concept

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

Step 2

Why this answer is correct

Thus \(A=\{0\}\), which has one element.

Step 3

Exam Tip

Identify ({0}) and \(\varnothing\) separately. चरण 1: \(x^2=0\) का पूर्णांक हल केवल (x=0) है। चरण 2: इसलिए \(A=\{0\}\), जिसमें एक अवयव है। चरण 3: ({0}) और \(\varnothing\) को अलग-अलग पहचानें।
