How to Get the Cubed Root on a TI-83 Plus

By Mandy Slake

The TI-83 is a scientific graphing calculator with many different functions. In fact, there are too many functions to fit directly on the keys. Some functions are placed under menu options or are secondary operations on the buttons. The cube root is the number that equals the answer when multiplied by itself three times. For example, the cube root of 27 is 3, because 3 x 3 x 3 = 27. You can access the cubed root function on the TI-83 Plus through a sub-menu using the MATH button.

Step 1

Press the "MATH" key on the TI-83.

Step 2

Press "4" to select the cube root function. The calculator will automatically insert a "(" to open the expression.

Step 3

Enter the expression or number. You can put in more than one number by enclosing the numbers in "{ }."

Step 4

Press ")" to close the parentheses and press "ENTER."
