What is ((-\infty,5)\cap[5,\infty)) on the number line?संख्या रेखा पर ((-\infty,5)\cap[5,\infty)) क्या होगा?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (\emptyset)(\emptyset)
The first part excludes (5), and the second starts at (5), so there is no common point. In exams, decide intersection only after checking endpoint inclusion.पहला भाग (5) को शामिल नहीं करता और दूसरा (5) से शुरू होता है, इसलिए कोई common point नहीं है। परीक्षा में endpoint inclusion देखकर ही intersection तय करें।
