किस विकल्प में \(2+\sqrt{3}\) का गुणनात्मक प्रतिलोम सही है?
Which option is the correct multiplicative inverse of \(2+\sqrt{3}\)?
Explanation opens after your attempt
Correct Answer
A. \(2-\sqrt{3}\)
Concept
(\(2+\sqrt{3}\)\(2-\sqrt{3}\)=1), so the inverse is \(2-\sqrt{3}\). In exams check that the product is (1).
Why this answer is correct
The correct answer is A. \(2-\sqrt{3}\). (\(2+\sqrt{3}\)\(2-\sqrt{3}\)=1), so the inverse is \(2-\sqrt{3}\). In exams check that the product is (1).
Exam Tip
(\(2+\sqrt{3}\)\(2-\sqrt{3}\)=1), इसलिए प्रतिलोम \(2-\sqrt{3}\) है। परीक्षा में गुणनफल (1) जांचें।
