I need to find cube roots, 4th, 5th etc roots. How do I do this on th TI-30XA calculator?

You can calculate cube roots by using the cube root function (the 2nd-shift of the 0 key). You can calculate arbitrary roots by using the x-root function (the 2nd-shift of the y^x key, just above the divide key).

Use the y^x key just above the divide key. For example, to raise 2 to the 4th power, press 2 y^x 4 =

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 =

On your calculator, in the 4th column and third row down you should see the root x symbol. In order to do a radical, just press a number and then press the root x and you shall get the square root of your number. Now in order to do this for cubed root, fourth root, etc, you have to hit the number you want to put in the radical, the 2nd key, look for the y^x key in the last column second row, and then the number outside the radical. For example, if you wanted to do the cubed root of 8, you would hit 8, 2nd y^x, 3, and you should get 2.

For cube roots, use the cube-root function in the MATH menu. For example, to calculate the cube root of 8, press MATH 4 8 =

For other roots (including cube root), use the xth-root function in the MATH menu. For example, to calculate the fifth root of 32, press 5 MATH 4 3 2 =

Use the x-root function, which is the 2nd function of the y^x key located just above the divide key. For example, to find the cube root of 8, press 8 2nd x-root 3 =

- Use the universal power key marked with [^].
- To avoid problems if the exponent is an expression, enclose it in parentheses.
- To enter any power type number^(exponent)
- If exponent is negative use the (-) change sign key next to the dot, below the 3 key.
- To calculate the roots (cubic, fourth, fifth, etc.) roots use the fact that a root of n-th order can be represented as ^(1/n)
- Ex: cube root of 27: 27^(1/3); square root of 64 : 64^(1/2) or 64^(0.5)

To extract the roots of orders higher than 2, you can use the universal power key labeled as [Y to x]. if the exponent is an integer 3, 4, 5, 6 etc.

it gives the cube the 4th power, 5th, 6th, etc.

If the exponent is 1/3, 1/4, 1/5, 1/6 you calculate the cubic root, the 4th root and so on.

When you use it to calculate the roots, the radicand (the number the root of which you are calculating) must be positive, otherwise you may get the result as a complex number.

The syntax of the command is value [Y to x] (1/ order of root)

Ex: cube root of 27 is entered as 27 [Y to x] (1/3)

it gives the cube the 4th power, 5th, 6th, etc.

Hello,

There is a relation between roots and fractionary powers.

2nd root (square root) of X = X^(1/2) power 1/2

3rd root (cubic root) of X = X^(1/3) power 1/3

4th root of X = X^(1/4)

...

n-th root of X = X^(1/n)

Use the raise to arbitrary power key labeled as a caret [^] or [X to the y] or [Y to the x]

Hope it helps.

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....

You use the y^x (y to the x) key along with the 2nd function key. That does the opposite operation.

So, let's pick something we know the answer to as an example. How about the cube root of 8? We know 8 = 2 X 2 X 2, so the cube root of 8 will be 2.

Here's how:

8 2nd y^x 3 =

The display will show 2.

The three is the root you want. You can put in any number, with 2 being the square root, 3 the cube root, etc.
