Could someone also help with this?

First of all, do we start at r = 0, or at r = 1? Also, shouldn't that expression at the end have absolute value signs around it, since it could be negative?

I think you start at r=0. Not sure about the absolute value signs though. The textbook only says what I've posted.

Integrand for this particular question type can we assume x>1 since the so called "Greatest coefficient" isn't the greatest if x=0.00000000000000000000000000000000000000000001

This one asked for coefficient, so we're only looking at binomial coefficients.

And of course, we can also see that the statement we're asked to prove is true by looking at rows of Pascal's Triangle.
