Question

If 2 = 1.4142, then what is root 2 -1 over root 2 
+1 ka square root

Answer 1

u mean
$\sqrt{ \frac{ (\sqrt{2}-1) }{ \sqrt{2}+1 } }= \sqrt{ \frac{( \sqrt{2}-1 )( \sqrt{2}-1 )}{( \sqrt{2}+1 )( \sqrt{2}-1 )} }$
$= \sqrt{ \frac{( \sqrt{2}-1 )^2}{2-1} }= |\sqrt{2}-1|=0.1892$
as $2=1.414= \sqrt{2},$
then $\sqrt{2}= \sqrt{ \sqrt{2} }=1.1892$

Answer 2
