I know, I know two threads in 5 minutes, but I can't get this one!
Binomial expansions are all fine and dandy, but when the exponent is a negative, a fraction, or both I am a little stumped.
Write the fourth term in the binomial expansion for:
(a - b)^-(1/5)
and I don't even know where to begin!

Ok, I think it's the same basic idea, you would just have an infinite number of terms. It's not easy to do.
