30xiis decimals square root


In general you cannot. If the square root happens to be an integer (ex: SQRT (4)=2) or a rational number (SQRT(16/9)=4/3) you can convert from one form to the other, but that is the same as converting from a decimal to a fraction.
However you can never convert 1.414213562 (the first 10 digits of SQRT(2)) into the radical SQRT(2). The reason is that root here is an irrational number: its decimal representation is endless and not periodic (non repeating).

How do you fix a "DOMAIN ERROR" ?


It depends on the function. The domain is the set of values that are permitted as input to the function. For the square root for example you cannot calculate square root of a negative number. If you type in sqrt(-3) you get a domain error.

If you are calculating inverse trigonometric functions such as arc sine and arc cosine the argument of the function must be in the closed interval [-1,1].

How to get the square root using a ti-30xa calculator?


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....
