Sum of radicals versus an integer[I made up the following (or rediscovered it).] Signature line: I wish a had a more interesting signature line. #2 20110519 09:46:34
Re: Sum of radicals versus an integerHi; Since both sides are positive we can square without changing the inequality. Subtract 5. Again we can square without changing the inequality. The second part we prove: Since both sides are positive we can square without changing the inequality. Subtract 12. Square again. So: Add them up. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof.
