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!
