6-√8 divide √2-1

agasfer [191]

Answer:

4 $\sqrt{2}$ +2

Step-by-step explanation:

$\frac{6-\sqrt{8}}{\sqrt{2}-1}$

= $\frac{6-\sqrt{8}}{\sqrt{2}-1}$ × $\frac{\sqrt{2}+1}{\sqrt{2}+1}$

= $\frac{(6-\sqrt{8})(\sqrt{2}+1)}{2-1}$

=6 $\sqrt{2}$ + 6 - $\sqrt{8}\sqrt{2}$ - $\sqrt{8}$

=6 $\sqrt{2}$ + 6 - 4 - $\sqrt{8}$

=6 $\sqrt{2}$ + 2 - $\sqrt{8}$

=6 $\sqrt{2}$ + 2 - 2

=4 $\sqrt{2}$ +2

for $\sqrt{8}$ = 2 $\sqrt{2}$ ,

$\sqrt{8}$ = $\sqrt{2*2*2}$

= ( $\sqrt{2}$ )^2 × $\sqrt{2}$

=2 × $\sqrt{2}$
