What is the rationalised form of \( \frac{5}{\sqrt{13}-\sqrt{8}} \)?
Explanation opens after your attempt
Correct Answer
A. \( \sqrt{13}+\sqrt{8} \)
Concept
Multiplying by the conjugate gives denominator (13-8=5). The numerator also has (5), so the answer is \( \sqrt{13}+\sqrt{8} \).
Why this answer is correct
The correct answer is A. \( \sqrt{13}+\sqrt{8} \). Multiplying by the conjugate gives denominator (13-8=5). The numerator also has (5), so the answer is \( \sqrt{13}+\sqrt{8} \).
Exam Tip
संयुग्मी से गुणा करने पर हर (13-8=5) आता है। अंश में भी (5) है इसलिए उत्तर \( \sqrt{13}+\sqrt{8} \) है।
