Question

solve this plz the answer is √b+a/b-a​

Answer 1

Step by Step Explanation :-

$\frac{b}{ \sqrt{ {b}^{2} - {a}^{2} } } + \frac{a}{\sqrt{ {b}^{2} - {a}^{2} }}$

=$\frac{(b + a)}{\sqrt{ {b}^{2} - {a}^{2} }}$

=$\frac{ \sqrt{ {(b + a)}^{2} } }{\sqrt{ {b}^{2} - {a}^{2} }}$

=$\frac{ \sqrt{(b + a)(b + a)} }{ \sqrt{(b + a)(b - a)} }$

=$\frac{ \sqrt{(b + a)} . \sqrt{(b + a)} }{ \sqrt{(b + a)}. \sqrt{(b - a)} }$

=$\frac{ \sqrt{(b + a)} }{ \sqrt{(b - a)} }$

=$\sqrt{ \frac{(b + a)}{(b - a)} }$
