It is obvious that Q_r$\mathbb{Q}_r$ is topologically isomorphic to Q_s while r$\mathbb{Q}_s$ where $r$ and s$s$ denote different primes.But But I really don't know whether it is true in the aspect of algebra.As As I failed to prove it,I I think that it is false,but but I can't give a counterexample. Last I'm quite sorry that I'm new to MathJax and I don't know how to use it properly.Thanks Thanks for reading and I would appreciate it if you could solve my problem.
