असमानता \(x^2\ge 64\) संख्या रेखा पर किस रूप में दिखेगी?
How will \(x^2\ge 64\) appear on the number line?
Explanation opens after your attempt
Correct Answer
C. (\(-\infty,-8]\cup[8,\infty\))
Concept
\(x^2\ge64\) gives \(|x|\ge8\), so two closed outer rays are obtained. In exams, include boundary points when the sign is \(\ge\).
Why this answer is correct
The correct answer is C. (\(-\infty,-8]\cup[8,\infty\)). \(x^2\ge64\) gives \(|x|\ge8\), so two closed outer rays are obtained. In exams, include boundary points when the sign is \(\ge\).
Exam Tip
\(x^2\ge64\) से \(|x|\ge8\), इसलिए बाहर के दो closed rays मिलते हैं। परीक्षा में \(\ge\) होने पर boundary points शामिल करें।
