1. The problem statement, all variables and given/known data
I'm a bit confused on how to add something like this $$\sqrt{}25$$+$$\sqrt{}30$$

2. Relevant equations

3. The attempt at a solution
I know this is an easy thing to do but im a little confused.

how else could you write root 25??

Oh i see. that wasnt a good example. how would you add $$\sqrt{}22$$+$$\sqrt{}30$$ that is wa better example of what i am trying to say. somthing that is not a perfect square.

You can't really express it more simply than it already is. You could write sqrt(2)*(sqrt(11)+sqrt(15)). But that's not really much, if any, simpler.

this is a problem I am working on (1+$$\sqrt{}26$$)(3-2$$\sqrt{}23$$
i simplified it down to 2$$\sqrt{}26$$*$$\sqrt{}23$$
if it was a normal problem without a number outside the radicals you would just take in both numbers inside a radical and multiply them but theres a 2 outside the radical of 26.

If you simplified (1+sqrt(26))*(3-2*sqrt(23)) down to 2*sqrt(26)*sqrt(23), you did it wrong. That's going to be ugly however you write it.
