Let F be an ordered field. We say that F has the Cauchy
Completeness Property if every Cauchy sequence in F converges in F.
Prove that the Cauchy Completeness Property and the Archimedean
Property imply the Least Upper Bound Property.
Recall:
Least Upper Bound Property: Let F be an ordered field. F has the
Least Upper Bound Property if every nonempty subset of F that is
bounded above has a least upper bound.
