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.

Why would I need to use square roots and cube roots?
Square roots and cube roots are mathematical operations that help us find the value that, when multiplied by itself (for square roots) or multiplied by itself twice (for cube roots), gives a specific number. They are useful in various fields such as engineering, physics, and computer science for calculations involving areas, volumes, and complex equations. Understanding square roots and cube roots allows for solving equations, simplifying expressions, and analyzing data more efficiently.
Why would you need to use square roots and cube root?
