यदि \(A={x:x\in \mathbb{Z}, x^2=16}\) और \(C=\{4\}\) हैं तो कौन सा सही है?

If \(A={x:x\in \mathbb{Z}, x^2=16}\) and \(C=\{4\}\) then which is correct?

Explanation opens after your attempt
Correct Answer

A. \(C\subset A\) और \(C\neq A\)\(C\subset A\) and \(C\neq A\)

Step 1

Concept

\(A=\{-4,4\}\), and \(C=\{4\}\) is its proper subset. Taking only the positive solution can cause an error.

Step 2

Why this answer is correct

The correct answer is A. \(C\subset A\) और \(C\neq A\) / \(C\subset A\) and \(C\neq A\). \(A=\{-4,4\}\), and \(C=\{4\}\) is its proper subset. Taking only the positive solution can cause an error.

Step 3

Exam Tip

\(A=\{-4,4\}\) है और \(C=\{4\}\) इसका उचित उपसमुच्चय है। केवल धनात्मक हल लेने से गलती हो सकती है।
