[Blindmath] help!!!! converting fractions into radical forms

[hpscheffer at aol.com]

Hi, my daughter is stuck on a problem and we can't find much help on video tutors or anywhere else on the web, can anyone help us with converting fractions into radical forms?


She has the following,


7 1/2 into radical form, she came to the conclusion of it being the square root of 15/2  would this be correct?


6 square root 2  she does not even know how to solve this one.


(5x)1/2


Any help would be greatly appreciated,


Heidi
