## anonymous 5 years ago square root of 8 over 8x^2

1. anonymous

$\sqrt(8/8x^2)$

2. anonymous

is this right?

3. anonymous

no $\sqrt{8}\div 8x ^{2}$

4. anonymous

okay thanks

5. anonymous

sqrt(8) can be written as sqrt(4)* sqrt(2)

6. anonymous

wait what i just want to know how to simplify it. i have teh answer in the book i just need help with the work. thats not the answer.

7. anonymous

sqrt(4) =2 so 2sqrt(2)/8x^2 sqrt(2)/4x^2

8. anonymous

my book says the answer should be 2sqrt(3)/3

9. anonymous

are you sure you're looking at the right problem? because you're not gonna be able to get rid of the x^2 on the bottom

10. anonymous

oh god your right. SORRY!! is sqrt(8)/ sqrt(6)

11. anonymous

okay for that you do the same thing as above. break the 8 up into 4 * 2 and break the 6 up into 3 * 2 . now you have :${\sqrt{4}\sqrt{2}} \over \sqrt{2}\sqrt{3}$ now just divide the sqrt(2) out

12. anonymous

${2 \over \sqrt{3}} \times {\sqrt{3} \over \sqrt{3}}$

13. anonymous

this will get rid of your radical on the bottom and change it to 3

14. anonymous

okay i think i get it. your doing a different way then what im used to but it makes sense

15. anonymous

how do you normally do it?

16. anonymous

heres and example our teacher would break sqrt(8) to the sqrt(2x2x2) and sqrt(6) to sqrt(2x3)
