Question

friends solve this question...

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

Answer 1

hey dude check it your answer
check it this screenshot
wait yrr
2(2a²-b²) /b²
first I rationalise
sorry for poor handwriting taking common in pic
hope it helps you

Answer 2

hey mate here's your answer
