Thread: Binomial Theorem - Prove that result is valid only for...?

Prove that if and only if for some positive integer

try it for small m, and use that (m n) = (m m-n) should be pretty obvious that if the condition doesn't hold the series doesn't 'telescope' into itself and leaves a remainder.
try the telescoping for small m if u want to see what's happening.

no real need for that, just need that (7 0) = (7 7), (7 1) = (7 6) etc.
