One rule, three different functions.
Answered
I'm trying to solve the equation
sqrt(x2sqrt(x1))=sqrt(x1)1.
To my surprise, Simplify(sqrt(x2sqrt(x1))) gives an unexpected result: sqrt(abs(x1))1.

Simplify will choose one of the branches in this case. For more control you can try:

"Assume(x>2,Simplify(sqrt(x2sqrt(x1)))) yields sqrt(abs(x  1)) + 1"
No, this yields sqrt(x  1) + 1.
How do I know I have to distinguish these two cases when solving my equation?

I think the correct answer must be abs(sqrt(x  1)  1)
