What is a cubed root?
A cubed root is the inverse operation of cubing a number. In other words, it is the number that, when multiplied by itself three times, gives the original number. For example, the cubed root of 8 is 2, because 2 * 2 * 2 = 8.
Cubic roots are often used in mathematics and science to solve equations and find solutions. They can also be used to simplify expressions and make them easier to work with.

3. Examples of finding cubed roots on a TI84 Plus
Here are some examples of how to find cubed roots on a TI84 Plus:
 To find the cubed root of 8, enter the following into the calculator:
“`
8 ^ (1 / 3)
“`
The calculator will then display the answer, which is 2.
 To find the cubed root of a negative number, you must first enter the number as a negative exponent. For example, to find the cubed root of 8, you would enter the following into the calculator:
“`
(8) ^ (1 / 3)
“`
The calculator will then display the answer, which is 2.
 To find the cubed root of a decimal number, you must first convert the number to a fraction. For example, to find the cubed root of 3.5, you would enter the following into the calculator:
“`
3.5 / 10 ^ 3
“`
The calculator will then display the answer, which is 0.577350269.
 To find the cubed root of a complex number, you must first convert the number to polar form. For example, to find the cubed root of 1 + 3i, you would enter the following into the calculator:
“`
polar(1 + 3i)
“`
The calculator will then display the following output:
“`
(2.014414874, 1.047197551)
“`
The first number in the output is the modulus of the complex number, and the second number is the argument of the complex number. To find the cubed root of the complex number, you must take the cube root of the modulus and multiply it by the complex number e raised to the power of the argument divided by 3. For example, to find the cubed root of 1 + 3i, you would enter the following into the calculator:
“`
3 ^ (1 / 3) * exp((1.047197551) / 3)
“`
The calculator will then display the answer, which is approximately 1.259921049 + 0.509903325i.
