How do you find cube roots on a TI-84 Plus?

Answer 1

For example, to find the cube root of 5x5x5=125. In order to have the calculator show the cube root of 125, you need to enter the numbers in the following format. 125^(1/3) If you enter that in your TI-84 Plus exactly as its written above, it should come up with 5 as the answer. Notice the (1/3) at the end. This is the "cube." If you want to find the root of a number to, say, the 5th power you would use the following format in the example problem below. Example problem: 4x4x4x4x4=1024 Format for calculator: 1024^(1/5) Basically you put the number in front, followed by the carrot symbol ( ^ ) with the fraction (1/5), the 5 being the power of the number (the amount of times you multiplied 4 to get 1024). You have to put it in parenthesis and you have to put it as a fraction with the power as the denominator.
