1. princeevee

$\sqrt{12/25}$

2. welshfella

you can write this as sqrt12 / sqrt25 also sqrt12 = sqrt4* sqrt3 can you see a way to simplify using the above?

3. princeevee

i dont get it : (

4. welshfella

do you know what the square root of 4 and square root of 25 are?

5. princeevee

2 and 5?

6. welshfella

right so plug these values in instead of the 2 square roots

7. princeevee

which is?

8. welshfella

|dw:1432937879842:dw|

9. princeevee

$\sqrt{2)\sqrt{3}}/5?$

10. welshfella

no - just replace the radicals ( that is the 2 with the square root signs you worked out just now) with their actual values

11. princeevee

12. welshfella

i cant give you the answer but i've explained how to get it - you had the 5 at the bottom of the fraction correct

13. princeevee

$4\sqrt{3}/5$

14. welshfella

almost - why the 4? - its the square root of 4

15. princeevee

$2\sqrt{3}/5$

16. welshfella

yes

17. welshfella

tghe way to do these is to try to factor the numbers so that factors include perfect squares another example would be sqrt ( 8/9) = sqrt8 / sqrt9 = sqrt4* sqrt2 / 3 = 2 sqrt2 / 3
