Question

$- \frac{1}{ \sqrt{2} - \sqrt{x} } =$
​

Answer 1

Resposta:

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