root of 75 + root of 3 = 6 root 3

3. anonymous

the last one is root of 21 + 7 root 2

4. anonymous

the first one i think is 3n^2 root 5n

5. anonymous

wait let me give you my answers

6. anonymous

5.) √45n^2 3√5 √n^5 3n^2 √5n 6.) √75 + √3 √25 * 3 + √3 5√3 + √3 = 6√3

7. anonymous

both correct

8. anonymous

Thank you I just cant do the third one

9. anonymous

distribute first

10. anonymous

like factor?

11. anonymous

Can you show me a step by step on how to solve this

12. anonymous

$\sqrt{7}(\sqrt{14}+\sqrt{3}) = \sqrt{21}+7\sqrt{2}$

13. anonymous

i dont know the steps i asked science

14. anonymous

7.) √7(√14+√3) √7(√2*7 + √3) √7 (√2√7+√3)

15. anonymous

go on

16. anonymous

idk how to do it from there @Dwayne_Johnson

@calculusxy

$\sqrt{7}(\sqrt{14}+\sqrt{3})=\sqrt{7}\sqrt{14}+\sqrt{7}\sqrt{3}=\sqrt{7}\sqrt{7*2}+\sqrt{7}\sqrt{3}=\sqrt{7}\sqrt{7}\sqrt{2}+\sqrt{7}\sqrt{3}\\=7\sqrt{2}+\sqrt{7}\sqrt{3}=7\sqrt{2}+\sqrt{21}$

thank you so much :)
