can you solve this in terms of combinatorics (chat gpt is using derivatives)?
I'm pretty sure it is combinatorics and derivatives, I think I remember this question

Idk if you have the solution (AI can often be wrong) so:
1. expand the given
2. differentiate both sides (i.e. the unexpanded and expanded form)
3. let x = 1

I haven't done the working on paper yet so I may be wrong but I believe this should work

If you haven't done any calculus yet then don't worry, it needs calculus as far as I'm aware

this is a standard type of binomial proof q-

all you have to do is to expand it using binomial theorem and diff both sides

lastly, just sub x = 1 in and you will get your answer;)

derive ≠ differentiate 😭
derivative ≠ derive 😭
