Is there any number from which you can extract the square root twice in a row and get an integer in the process(i.e.i.e., (x^1 2)^1 2))?

Take any number, raise to power 4, for example 2^4=16, and safely extract the root twice, getting back 2. To get you down to 140 characters, I'll tell you "the square root twice in a row" - is the square root of the 4th degree.
