\( \frac{1}{4\sqrt{3}+3\sqrt{5}} \) का परिमेय हर वाला रूप क्या है?
What is the rationalised form of \( \frac{1}{4\sqrt{3}+3\sqrt{5}} \)?
Explanation opens after your attempt
Correct Answer
A. \( \frac{4\sqrt{3}-3\sqrt{5}}{3} \)
Concept
Multiplying by the conjugate gives denominator (48-45=3). So the form is \( \frac{4\sqrt{3}-3\sqrt{5}}{3} \).
Why this answer is correct
The correct answer is A. \( \frac{4\sqrt{3}-3\sqrt{5}}{3} \). Multiplying by the conjugate gives denominator (48-45=3). So the form is \( \frac{4\sqrt{3}-3\sqrt{5}}{3} \).
Exam Tip
संयुग्मी से गुणा करने पर हर (48-45=3) आता है। इसलिए रूप \( \frac{4\sqrt{3}-3\sqrt{5}}{3} \) है।
