Question

racionalize a fração; v2/v2+1

Answer 1

$\dfrac{ \sqrt{2} }{ \sqrt{2} + 1}$

$\dfrac{ \sqrt{2} }{ \sqrt{2} + 1} \times \dfrac{ \sqrt{2} - 1 }{ \sqrt{2} - 1 }$

$\dfrac{ \sqrt{2}( \sqrt{2} - 1) }{( \sqrt{2} + 1)( \sqrt{2} - 1) }$

$\dfrac{ \sqrt{2}( \sqrt{2} - 1) }{2 - 1}$

$\dfrac{ \sqrt{2}( \sqrt{2} - 1) }{1}$

$2 - \sqrt{2}$
