Press the diamond key, then press ENTER to convert a symbolic result to a decimal result. If you want them all in decimal form, press MODE then F2. Scroll down to Exact/Approx and change that setting to Approximate.

SOURCE: Finding a cube root on 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).

How to calculate cube root on simple calculator


That depends on how simple a calculator. I'll give some examples below for calculating the cube root of 8.

On a TI-86, press 3 2nd [MATH] F5 MORE F4 8 ENTER

If the calculator has a "^" or "y^x" key, raise 8 to the 1/3 power. Again, on the TI-86, press 8 ^ ( 1 / 3 ) ENTER

If the calculator has a logarithm key, take the logarithm, divide it by three, then take the antilogarithm. Again, on the TI-86, press 2nd [e^x] ( ln 8 / 3 ) ENTER

On a slide rule, place the hairline over the number on the K scale and read the cube root on the D scale.

Cube roots


The TI-89 does not have a cube root function. However, you can calculate any root simply by raising to the reciprocal of the power. For example, to calculate the cube (third) root of 125, press
5 ^ ( 1 / 3 ) ENTER

How can I find the square root of 39 on my ti-30xa? Also I would like to know how to find the cube of 9482... Help


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 =
