समुच्चय \(A={x\in\mathbb{Q}:x^2=0.25}\) के बारे में सही कथन कौन सा है?
Which statement is correct about the set \(A={x\in\mathbb{Q}:x^2=0.25}\)?
Explanation opens after your attempt
B. \(A=\{-0.5,0.5\}\), परिमित\(A=\{-0.5,0.5\}\), finite
Concept
\(0.25=\frac{1}{4}\) है। / \(0.25=\frac{1}{4}\).
Why this answer is correct
\(x^2=\frac{1}{4}\) के परिमेय हल \(x=\frac{1}{2}\) और \(x=-\frac{1}{2}\) हैं। / The rational solutions of \(x^2=\frac{1}{4}\) are \(x=\frac{1}{2}\) and \(x=-\frac{1}{2}\).
Exam Tip
वर्ग समीकरण में धन और ऋण दोनों मान शामिल करें। / Include both positive and negative values in a square equation.
