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

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

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

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

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 ;)
