Answer 1

Step-by-step explanation:

$\sqrt{ \frac{1 - \sqrt{x} }{1 + \sqrt{x} } } \\ = \sqrt{ \frac{(1 - \sqrt{x})(1 - \sqrt{x}) }{(1 + \sqrt{x})(1 - \sqrt{x}) } } \\ = \sqrt{ \frac{ {(1 - \sqrt{x}) }^{2} }{ {1}^{2} - { \sqrt{x} }^{2} } } \\ = \sqrt{ \frac{(1 - \sqrt{x})^{2} }{1 - x} } \\ = \frac{1 - \sqrt{x} }{ \sqrt{1 - x} }$
