कौन सा विकल्प सही प्रतिउदाहरण है कि दो अपरिमेय संख्याओं का योग हमेशा अपरिमेय नहीं होता?
Which option is a correct counterexample showing that the sum of two irrational numbers is not always irrational?
Explanation opens after your attempt
Correct Answer
A. \(\sqrt{8}\) और \(-\sqrt{8}\)\(\sqrt{8}\) and \(-\sqrt{8}\)
Concept
(\sqrt{8}+\(-\sqrt{8}\)=0), which is rational. In exams one counterexample is enough to disprove a universal statement.
Why this answer is correct
The correct answer is A. \(\sqrt{8}\) और \(-\sqrt{8}\) / \(\sqrt{8}\) and \(-\sqrt{8}\). (\sqrt{8}+\(-\sqrt{8}\)=0), which is rational. In exams one counterexample is enough to disprove a universal statement.
Exam Tip
(\sqrt{8}+\(-\sqrt{8}\)=0), जो परिमेय है। परीक्षा में गलत सार्वत्रिक कथन तोड़ने के लिए एक प्रतिउदाहरण काफी है।
