Take the antilog of (1/3) of the log of the number you want the root for.

Alternatively, type in X^(1/3)

Well, heck, I can't answer that one but perhaps you can get a better response here:

The TI-89 has one function to find whatever root you want of a number.

To find the cubed root of say...64, you would type:

root(64,3)

How do you calculate the cubed root of a number or 5th root of a number?


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 =

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.
