SOURCE: 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....

SOURCE: square roots

One way is you get square root by raising to the (1/2) power. For example square root of 16 is

16^(1/2).

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

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.

SOURCE: how do i put the square root of a problem in a TI

Hello,

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.

Square root of 39: Press 3 9 [square-root] =

[square-root] is the key just to the left of the divide key.

Cube root of 9482: Press 9 4 8 2 2nd [cube-root] =

[cube-root] is the shifted function of the 0 key.

For other roots, you can use the [nth-root] function, the shifted function of the key above the divide key. For example, to calculate the fourth root of 16, press 1 6 2nd [nth-root] 4 =

[square-root] is the key just to the left of the divide key.

You don't want the square root. In this example, you want the sixth root.

Press 4 5 2nd [xth-root] 6 =

The xth-root is the shifted function of the y^x key, located just above the divide key.

Press 4 5 2nd [xth-root] 6 =

The xth-root is the shifted function of the y^x key, located just above the divide key.

The square root of a negative number is an imaginary number, and the TI-30XA does not deal with imaginary numbers.

However, the square root of -x is equal to i times the square root of x. So, to calculate the square root of -4, for example, press 4 square_root = and read 2. Thus the square root of -4 is 2i.
