MATH 413 [513] (PHILLIPS) SOLUTIONS TO HOMEWORK 1
Generally, a “solution” is something that would be acceptable if turned in in the form presented here, although the solutions given are often close to minimal in this respect. A “solution (sketch)” is too sketchy to be considered a complete solution if turned in; varying amounts of detail would need to be ?lled in. Problem 1.1: If r ∈ Q ￦ {0} and x ∈ R ￦ Q, prove that r + x, rx ∈ Q. Solution: We prove this by contradiction. Let r ∈ Q￦{0}, and suppose that r +x ∈ Q. Then, using the ?eld properties of both R and Q, we have x = (r + x) ? r ∈ Q. Thus x ∈ Q implies r + x ∈ Q. Similarly, if rx ∈ Q, then x = (rx)/r ∈ Q. (Here, in add…(skip)
