MC II-B HW Questions
For 6.26, I can see the pattern and I know that I should use the binomial theorem, but I don't really know how I should apply the binomial theorem here.
For 6.27-28, I don't how to start them.
For 6.30, I'm assuming you use the binomial theorem and then use symmetry, but I'm not sure how to apply them.
Thanks! And Happy (early) MLK Day.
