I know how to do a case-by-case proof, but I'd like to see one that is true for all cases where an infinite sum of rationals yield an irrational.
OpenStudy (anonymous):
"can" means you only need one example. so there would be no "general" way to do it because it is not true in general
OpenStudy (anonymous):
You're right. I should have said "demonstrate rigorously the conditions under which an infinite sum of rationals will yield an irrational".
