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.

Some calculators have a cube root function
Cube root of 510 is 7.989569740454013. You can find cube roots easily by using the calculator under related links.
2.7589.... If you don't have cube roots on your calculator, find the logarithm of 21, divide it by 3, and find the antilog of that.
For school you will need to learn how to find square and cube roots in order to have the needed prerequisites to answer progressively harder and more complex problems.

The real cube root of 1 is 1, since 13 = 1. There also a pair of complex cube roots.
You can find the roots with the quadratic equation (a = 1, b = 3, c = -5).
Many calculators will offer a way for you to do cube roots, or what number to the power of 3 will equal that number. There is no easy way to go about finding cube roots without a calculator, so I suggest not trying too hard.. but the cube root of 7 is 1.912931182772389 found from using a simple Cube Root calculator you can find on the internet.
The four roots are:1 + 2i, 1 - 2i, 3i and -3i.
yes, you can find a real root to the cube root of any negative real number. There will also be two complex roots which satisfy it, as well.
Most square roots, cube roots, etc. - including this one - are irrational numbers. That means you can't write them exactly as a fraction. Of course, you can calculate the cubic root with a calculator or with Excel, then find a fraction that is fairly close to it.
