## anonymous 5 years ago sqrt{(1-sqrt{x})/(1+sqrt{x})}

1. anonymous

$\sqrt{(1-\sqrt{x})/(1+\sqrt{x})}$

2. anonymous

$\int\limits_{}^{}\sqrt{(1-\sqrt{x})/(1+\sqrt{x})}$

3. anonymous

I would start by substituting u=sqrtx.

4. anonymous

Oh wait!! I didn't see the big square root =).

5. anonymous

Using the formula (a+b) (a-b) = a^2 - b^2 You get 1 - x under the big root sign

6. anonymous

Sorry, It has a divide sign !!!

You can rationalise by multiplying the number under the big root sign by $1 - \sqrt{x}$ -------------- $1 - \sqrt{x}$
