    cube root on the calculator?

    How do you graph the cube root function on a calculator I have a TI83+

    Ive looked in catalog none there I know how to do the Root then the x inside the root but how do you add the three in front

    there is probably a \boxed{\sqrt[3]{x}} button, if not, there is a \boxed{\sqrt[x]{\color{white}....}} button (it is usually the second function on the \boxed{y^x} button). if all else fails, note that taking the cube root is the same as raising to the 1/3 power

    I definitely remember there being those buttons on my [old] TI-83, however raising to the 1/3rd power is much more convenient, and learning to think about cubic roots (and square roots, etc.) in this form is very useful as you progress in mathematics.
