Sum of rootsHow many ordered pairs of nonnegative integers (a,b) are there such that √a+√b=√432 ? 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.' 'God exists because Mathematics is consistent, and the devil exists because we cannot prove it' 'Who are you to judge everything?' Alokananda #2 20130417 00:17:13
Re: Sum of roots
Won’t there actually be 13 ordered pairs (because of the 0)? 134 books currently added on Goodreads #3 20130417 00:18:56
Re: Sum of rootsI am getting 6 with a>b. 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. #4 20130417 00:29:01
Re: Sum of rootsOh yeah! I missed the question totally 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'
