Jason Bourne; In the past you have gotten rather extensive help. But now you need to at least show some effort on your part. This is simply a list of question leading to an overall result.

At least show that you understand part (a). How do you think it is worked?

For part (b), what do you understand about the addition of rational numbers and irrational? What could that answer have to do with part (b)?

Please tell us what you don’t understand.
