This is the answer for part a.Whenever you see two functions in the same bracket,you can answer the qn with two ways..I recommend you use the general term(2nd option) as it more smooth and effective.Using general term in finding coefficient related qn would certainly help a lot..I'll show you the rest except part b..Use the same method to do b..Hope this helps. :)

By the way,for option 1,you can expand using the general term for (1-(1/2x^3))^20.Then,you can move on to combine them(with the other).
