Everything the word "Root" comes up
When you load the DVD, instead of the content loading, the word "Root" comes up? This means the content is either corrupted, the disc is dirty, or damaged. In other words, the laser is not able to reach and pick up the magnetic information on the disc. Does this happen with another DVD player? Try doing that first. In the meantime, clean the disc. If the disc can't be read by another DVD player, then the disc is at fault. If another DVD player can load the disc with no problem, the original DVD player you used, may have a dirty lens (what the laser shoots out of), or the laser is not moving at all. If this is the case, the DVD player is broken.

SOURCE: Graphing radical functions
I have a TI-89 Titanium and I have experienced the same problem. HERE IS HOW TO FIX IT:
Goto " MODE " and scroll down the options until you get to
" COMPLEX FORMAT " change that option to " RECTANGULAR " and press ENTER until you exit out of the " MODE " screen. (very important that you press ' enter ' until you exit because if you don't, it will not save your changes. )

SOURCE: TI-15 square root Function
You should enter it as follows [SQRT]36 ) [ENTER/=].
If you define some function f of a variable x you write that f(x), where the parentheses enclose the so-called argument (objet on wich the function acts). It seems that on this calculator the opening parenthesis is implicit: the calculator supplies it when you press [SQRT] but does not display it (a design flaw?). However the closing parenthesis must be entered by you to signifie to the function [SQRT] that you have finished entering the argument. Weird but one can live with it.
Hope it helps.

The square root has a dedicated key sequence [2nd][V square root symbol]
Square root of 21.2846 is entered [2nd][V square root] 21.2846 [ENTER] .
The result is`4.614.
I suspect you want to calculate the 4th root of 21.2846. If it is the case you enter that as
21.2846 [^](1/4) =2.148
Square root can be also entered as [^](1/2)
Cube root is entered as [^] (1/3)
nth root is entered as [^](1/n)
Hope it helps.
