That's the million dollar question! I had a similar post several weeks ago, only that in my case I took it a bit further and I wanted to make Simplify produce for example A, where I have A=1/Sqrt[1 + 1/x] I'm pretty sure Mathematica is well aware that the two are equal but I couldn;t figure out how to tell it to substitute different forms and rearrange expressions the way I want them! Let me know if you make any progress on the issue!
