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....

One way is you get square root by raising to the (1/2) power. For example square root of 16 is
You can use this method to get the other "roots" as well e.g. 1/3, 1/4, etc.

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.

Use the square root key accessed after pressing the [2nd] function key.
Press [2nd] [Square root key] 121 [ ) ] [ENTER]. Do not forget the right parenthesis, even if you did not have to enter the left parenthesis.
The result should be 11 (one of the square roots to remember).
Hope it helps.
