when can you simplify surds watch

1. what is the exception of simplifying surds, for example if it is in a fraction.
you can't simplify the number in the sur. for example:

9root3 / 3
is simplified to 3 root 3
why don't you simplify the root three
2. 9root3/3 is just saying (3x3xroot3)/3 so you cancel the threes. There's nothing to simplify the root three with.
3. You can simplify surds where's it's like

2x root2
---------- = 2 root2
x root2
4. Let's look at 9root3 /3

let's call root3 x for now

You have 9x /3 so that leaves you 3x

Sub back in.
3 root3

You have a whole number and a surd part.
