What is the rationalised form of \(\frac{6}{\sqrt{19}-\sqrt{10}}\)?
Explanation opens after your attempt
Correct Answer
C. (\frac{6\(\sqrt{19}+\sqrt{10}\)}{9})
Concept
Multiplying by the conjugate makes the denominator (19-10=9). So the form is (\frac{6\(\sqrt{19}+\sqrt{10}\)}{9}).
Why this answer is correct
The correct answer is C. (\frac{6\(\sqrt{19}+\sqrt{10}\)}{9}). Multiplying by the conjugate makes the denominator (19-10=9). So the form is (\frac{6\(\sqrt{19}+\sqrt{10}\)}{9}).
Exam Tip
संयुग्मी से गुणा करने पर हर (19-10=9) बनता है। इसलिए रूप (\frac{6\(\sqrt{19}+\sqrt{10}\)}{9}) है।
