4. emily9102

1?

5. emily9102

6. emily9102

i don't get what i'm supposed to do

ok,if you simplify the roots, you will get |dw:1342583504244:dw|

9. ganeshie8

25, 4 and 9 are perfect squares. so you can take them out of radical by taking their square root

10. emily9102

ok

11. ganeshie8

|dw:1342583591956:dw|

12. ganeshie8

after this, see @sritama drawing above... :)

15. emily9102

now do i combine or something?

16. ganeshie8

|dw:1342583827293:dw|

17. ganeshie8

yup !! since they both have a factor of same radical term, you can combine those both

19. ganeshie8

looks perfect :D

20. emily9102

Yep it was correct!

21. ganeshie8

btw ur drawings are much better in this post :))

22. emily9102

Haha. I took a 15 minute art lesson just for you :p

23. ganeshie8

lol appreciate it heartfuly ;)

24. emily9102

Lol, are you like a math teacher or something? Or is there a program you use to figure this out?

25. ganeshie8

im not a teacher.... practice and some guessing is working for me hehe

26. emily9102

oh ok :)

27. ganeshie8

these questions, which involve simplifying stuff... you need to do some guessing to figure out, "how to factor things inside radicals in terms of perfect squares." once you do few problems i guess you wud become comfortable ;)

yeah, my test is thursday so im trying to understand everything :/
