\(\frac{4}{\sqrt{10}-\sqrt{6}}\) का परिमेयकृत रूप कौन-सा है?
Which is the rationalised form of \(\frac{4}{\sqrt{10}-\sqrt{6}}\)?
Explanation opens after your attempt
Correct Answer
A. \(\sqrt{10}+\sqrt{6}\)
Concept
Multiplying by the conjugate makes the denominator (10-6=4). So (\frac{4\(\sqrt{10}+\sqrt{6}\)}{4}=\sqrt{10}+\sqrt{6}).
Why this answer is correct
The correct answer is A. \(\sqrt{10}+\sqrt{6}\). Multiplying by the conjugate makes the denominator (10-6=4). So (\frac{4\(\sqrt{10}+\sqrt{6}\)}{4}=\sqrt{10}+\sqrt{6}).
Exam Tip
संयुग्मी से गुणा करने पर हर (10-6=4) बनता है। इसलिए (\frac{4\(\sqrt{10}+\sqrt{6}\)}{4}=\sqrt{10}+\sqrt{6}) है।
