How to Find Cube Root in Ti-84

By Mark Kennan

The cubic root of a number multiplied by itself three times equals the original number. For example, the cube root of 27 equals three because 3 times 3 times 3 equals 27. The cubic root, however, is not always so easy to calculate. In such cases, using the TI-84 to figure the cube root is much easier.

Push the "Math" button on the calculator.

Push the "4" key to select the cube root function.

Enter the number you want to find the cube root of. For example, if you want to find the cube root of 8, enter "8."

Push "Enter" to have the TI-84 display the cube root. In this example, the TI-84 will show the cube root of 8 to be 2.
