3 Radical 81 + 2 Radical 25 = ?

I am stuck on the whole thing. I don't understand how to add them.
Could you e-mail me about adding the two together?  Thanks.

THANKS Lost in adding square roots......

Sometimes radical questions are really hard to figure out, but
this one should work out pretty well.

First work on \/81  ( that is how I will notate radical)

What is the number that when squared gives us 81?

I hope you see that it is 9. So the first part is 3*9,
which is 27.

How would you figure out the second part?

Then after you have the two parts add them together.

Hope that helps.
