यदि \(a=\sqrt{5}+\sqrt{3}\) और \(b=\sqrt{5}-\sqrt{3}\) हैं तो \(\frac{a}{b}\) का सरल रूप क्या है?
If \(a=\sqrt{5}+\sqrt{3}\) and \(b=\sqrt{5}-\sqrt{3}\), what is the simplified form of \(\frac{a}{b}\)?
Explanation opens after your attempt
A. \(4+\sqrt{15}\)
Concept
Multiplying by the conjugate gives denominator (5-3=2) and numerator \(8+2\sqrt{15}\). The simplified form is \(4+\sqrt{15}\).
Why this answer is correct
The correct answer is A. \(4+\sqrt{15}\). Multiplying by the conjugate gives denominator (5-3=2) and numerator \(8+2\sqrt{15}\). The simplified form is \(4+\sqrt{15}\).
Exam Tip
संयुग्मी से गुणा करने पर हर (5-3=2) और अंश \(8+2\sqrt{15}\) बनता है। सरल रूप \(4+\sqrt{15}\) है।
