\( \frac{1}{\sqrt{13}+\sqrt{12}} \) का परिमेय हर वाला रूप क्या है?
What is the rationalised form of \( \frac{1}{\sqrt{13}+\sqrt{12}} \)?
Explanation opens after your attempt
Correct Answer
A. \( \sqrt{13}-2\sqrt{3} \)
Concept
The denominator is \( \sqrt{13}+2\sqrt{3} \) and its conjugate is \( \sqrt{13}-2\sqrt{3} \). The denominator becomes (13-12=1).
Why this answer is correct
The correct answer is A. \( \sqrt{13}-2\sqrt{3} \). The denominator is \( \sqrt{13}+2\sqrt{3} \) and its conjugate is \( \sqrt{13}-2\sqrt{3} \). The denominator becomes (13-12=1).
Exam Tip
हर \( \sqrt{13}+2\sqrt{3} \) है और संयुग्मी \( \sqrt{13}-2\sqrt{3} \) होगा। हर (13-12=1) बनता है।
