3$\sqrt{2}$

#### Explanation:

start off by simiplying the $\sqrt{8}$ :

$\sqrt{8}$ = $\sqrt{4 \cdot 2}$

$\sqrt{4}$ = 2

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

2$\sqrt{2}$ + $\sqrt{2}$

= 3$\sqrt{2}$

Well it is

$\sqrt{8} + \sqrt{2} = \sqrt{{2}^{2} \cdot 2} + \sqrt{2} = 2 \sqrt{2} + \sqrt{2} = 3 \cdot \sqrt{2}$
