Adding Square RootsDate: 10/31/95 at 18:46:16 From: Anonymous Subject: Help in math so I can teach... 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......

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. -Doctor Ethan, The Geometry Forum |
