It looks like that

3. anonymous

$\sqrt{2}(\sqrt{2}\times3+\sqrt{18})=\sqrt{2}(\sqrt{2}\times3+\sqrt{2}\sqrt{9})$ $\sqrt{2}(\sqrt{2}\times3+\sqrt{2}\times3)=\sqrt{2}(\sqrt{2}\times6)$

4. anonymous

$\sqrt{2}\times \sqrt{2} \times 6=2 \times 6$

5. anonymous

you got the idea?

6. anonymous

So you don't distribute the √2 ?

7. anonymous

no not until you deal with the sqrt18

8. anonymous

sqrt to outside can wait
