Come on now....there are dedicated "square" and "square root" keys on the TI-30XA....
Enter your number e.g. 4, then press the "root x" key to get 2...
Press "x squared" key to get the square of 2 = 4
There's the even more useful "y to the power x" key and it's inverse "xth root of y" key.
E.g. Enter 2, then press the "y to the power x" key, then 5, then =, answer is 32 (2 x 2 x 2 x 2 x 2). Starting with 32, pres 2nd then the "y to the power x" key, then 5, then =, answer is 2, the 5th root of 32....

It's been a while since my TI calculator died, but I think you can just hit EE (may be "exp" on your model) followed by =.

Hello,
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.
