Could someone help me with square roots. I have looked on many different site and I can't find what I'm looking for. If anyone could please give me a good site that explains square roots I would appreciate it. If I have numbers with different roots how do I add them? EX. 5 SQRT 4 + 6 sqrt 3. How do I simplify? Also sqrt of 75/25. I can't find any explainations!
