Hiow to evaluate

Using the binomial theorem

l is a non negative integer.

I don't know how to proceed. Is there another way?

Thanks.

Move the differential operator into the sum. You'll need to evaluate

which you can easily do by induction. Some terms of the sum may vanish while doing this, I didn't check. Finally, swap the sum and integral. Evaluate the integral. And you should be done.
