I know this is an easy thing to do but I am a little confused.

how else could you write root 25??

 

[Stratosphere]

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 there's a 2 outside the radical of 26.

 

[Dick]

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.

so you can't add the two up?

 

[Dick]

Not in any simple way, no.
