Square root: how do I start sqrt 4/25

I got the sqrt of the 4 which was 2
then the sqrt of 25 is 5
The answer would be

sqrt(2/5)

One of the rules for radicals says this:

sqrt(a/b) = sqrt(a) / sqrt(b)

So....

sqrt(4/25) = sqrt(4) / sqrt(25)

You know what sqrt(4) and sqrt(25) are, right?
 
Yes I post the answer and It's sqrt (2/5)
I had it down.

I guess I got it right

No, that's not right.

sqrt(4) = 2

sqrt(25) = 5

sqrt(4/25)= sqrt(4) / sqrt(25) = 2/5


NOT sqrt(2/5)......
 
sorry thats right I wasn't supposed to right that. I just have 2/5 on my paper
thanks again
