Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: ((-\infty,-4]\cup[4,\infty))((-\infty,-4]\cup[4,\infty))
(x^2\ge 16) means (|x|\ge 4), giving two closed outer regions. In exams, include (-4) and (4) for (\ge).(x^2\ge 16) में (|x|\ge 4), इसलिए बाहर के दो closed भाग मिलते हैं। परीक्षा में (\ge) होने पर (-4) और (4) शामिल करें।
