- Let ab in a field F. Show that x+a and x+b are relatively prime in F[x].Prove that if R and S are fields, then the direct sum RS is not a field. [Type here][Type here]Since this section presents a method for constructing a field of quotients for an arbitrary integral domain D, we might ask what happens if D is already a field. As an example, consider the situation when D=5. a. With D=5, write out all the elements of S, sort these elements according to the relation , and then list all the distinct elements of Q. b. Exhibit an isomorphism from D to Q.
- Suppose S is a subset of an field F that contains at least two elements and satisfies both of the following conditions: xS and yS imply xyS, and xS and y0S imply xy1S. Prove that S is a field. This S is called a subfield of F. [Type here][Type here]8. Prove that the characteristic of a field is either 0 or a prime.[Type here] True or False Label each of the following statements as either true or false. 3. Every integral domain is a field. [Type here]
- If e is the unity in an integral domain D, prove that (e)a=a for all aD. [Type here][Type here]Label each of the following as either true or false. If a set S is not an integral domain, then S is not a field. [Type here][Type here]14. a. If is an ordered integral domain, prove that each element in the quotient field of can be written in the form with in . b. If with in , prove that if and only if in .
