HOW TO FIND CUBE ROOT OF A NUMBER ON fx-82ms


There are several ways to find the cube root of a number on a calculator. On this calculator, we can use the nth root button, by using the yellow shift button with the ^ key. Another way to do this is just to use the ^ key.

For example, the cube root of 8 is performed by the following key sequence: 8, shift, ^, 3.

Another sequence is: 8 ^ (1/3)

Good luck.

Paul

How do i do radicals expressions on a TI 30XA


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.

You can multiply a number by 1/3rd to get the cube root or

Under the MATH button, the fourth option down will give you cube root. Any n root beyond that will require the x^(1/n) method.

Entering a cubed root into a ti-83 plus


You can enter any root by typing the number, then hitting MATH and 5, which brings up the root symbol with the x in front of it: x√. So the fifth-root would be 5 -> MATH -> 5 and then whatever number you want to get the fifth-root for: 5x√10 for example. As someone else had mentioned, you can also raise it to a rational power: 3^(1/3) which would be the same as the cubed root of 3, but you could also type: 3 -> MATH -> 5 -> 3 and get the same answer, but looking like this in your calculator: 3x√3. The option for 4 actually is a predefined cubed-root, and the one for option 5 there is the root symbol that can be used with any number before it to get any root you want. There are no parenthesis as you get when using the predefined square-root and cubed-root functions, though, so you may want to type them in yourself if entering a long string of operations in the calculator at one time to make sure the calculator doesn't include numbers under the root that you don't want it to. But I guess it depends on preference in terms of what method you choose between the rational exponents or the root symbol (and most would go with whichever seems easiest and quickest to enter), but you asked specifically how to get the cubed-root on the TI-83 Plus, so there's my best attempt at answering your question.

Cube roots


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.
