The solution begins by expanding using the binomial theorem, but b is a real-valued constant (e.g., b = pi would be a possible setting). I'm not sure if I misunderstood the question but this seems like an incorrect application of the expansion since b would have to be an integer.
Hi.
Exercise 3.1-2 asks:![image](https://user-images.githubusercontent.com/52089815/138174590-e27f57c7-01c0-4798-b41b-0a7bc166b0b9.png)

Appreciate any replies to clarify this. Thanks!
