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
A. \(C\subset A\) और \(C\neq A\)\(C\subset A\) and \(C\neq A\)
Concept
\(A=\{-4,4\}\), and \(C=\{4\}\) is its proper subset. Taking only the positive solution can cause an error.
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.
Exam Tip
\(A=\{-4,4\}\) है और \(C=\{4\}\) इसका उचित उपसमुच्चय है। केवल धनात्मक हल लेने से गलती हो सकती है।
