Looking at the buutons, it is at the far left, 5th down it says x2 put the number before it then click that button and then it should square

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.

Hi shiny_diamon
Here is a picture of the powers and root functions of your calculator.
1.To calculate the cubic root of a number you use the key combination shown on line 5
Ex: Cubic root of 27
27 [2nd] [3 root x] [EXE]; Should get 3
2. You can use the general root key on line 7 [2nd][x Root y]
Ex: Cubic root of 125
125 [2nd][ x Root y] 3 [EXE] Should get 5
(-125) [2nd][x Root y] 3 [EXE]; Should get -5
3. You can also yse the general power key on line 6: [Y to x], but the degree of the root is entered as a fraction 1/3
Ex: cubic root of -125.
(-125) [Y to x]( 1/3) [EXE]; You should get -5
4. The [Y to x[ key is the one you use to obtain all other roots fourth, fift, tenth, n-th.
Ex: Fourth root of 256
256 [Y to x] (1/4) [EXE]: You should get 4
5. To extract the squqre root of a number you can use the key on the 3rd line [root x] or the general power key on line 6 with exponent 1/2
Exemple square root of 256
256 [Root x] [EXE] should give you 16
256 [Y to x] (1/2) [EXE] should give you 16 also
Hope that helps.

It may be that you have somehow changed to a 'mode' that only shows integer values.
Try pressing the green button, then 5, then 9. Then try the calculation again.
If this fails, you can use Google as a calculator - search Google for sqrt(0.4053) and see what happens.. :-)
SOURCE: I have a T1 30xs,
The calculator is able to display fractions and certain irrational number as radicals. However there is the twosided arrow key to
toggle between exact and approximate (decimal).
Here is a screen capture from the manual to give you some more informations.
SOURCE: convert square root to decimal TI-30XA
Press 2nd then F--D key(its means left arrow key or left key from zero)
