Show that the given map is surjective. Please give a detailed,
thorough formal explanation/proof. It's somewhat obvious it is
surjective, but I don't know how to start the proof. We are
supposed to take y element of codomain and show that there exists
f(x) = y but where is the codomain and where is the domain?
Somewhat confused since we have two binary structures. Thanks!

question 1 to question 5
Given an integral domain R we define the relatic n~on Rx (R (0]) by (a, b)~(c, d) means ad bc. We also define the following operations on R x (R\o) (a, b) + (c, d) (ad + be, bd) and (a, b) (c,d) (ac, bd). 1. Prove that ~ is an equivalence relation. 2. Prove that ~is compatible with +and . (Therefore, ~is a congru- 3. Conclude that the following...
