Radical Notations
The properties that allow us to handle radical numbers in mathematical operations are:
For example: 
. The same property can be used to simplify the radical. 
which can be written as 
.
Note that you can not multiply (or divide) 
and 
- the root indices (2 and 3) are different.
You will note that there are no properties for add and subtract. The distributive property allows us to do these operations.
Note that you can not add 
and 
. Since the number inside the root sign is different, it is not possible to factor the radical part out.
