HOW TO FIND CUBE ROOT
There is a way to do it. I believe you go into "complex" or "math" buttons. These buttons are yellow on the calculator. Therefore, to access them you must hit "2nd" then the button.
Better yet, you can also get around this dilemma another way. You can enter "the cubed root of x" by raising x to 1/3.
For example the cubed root of x = x^(1/3). It is best to place parentheses around 1/3 so the calculator knows exactly what you mean.
Another example, the "cubed root of (x + 1)" can be entered by:
(x+1)^(1/3) Note the parenteses around both (x+1) and (1/3). This applies if the radical cover both "x" and "1".
Hope this helps.

How do I find the cube root button on my TI- 86
There is a relation between roots and fractionary powers.
2nd root (square root) of X = X^(1/2) power 1/2
3rd root (cubic root) of X = X^(1/3) power 1/3
4th root of X = X^(1/4)
n-th root of X = X^(1/n)
Use the raise to arbitrary power key labeled as a caret [^] or [X to the y] or [Y to the x]
Hope it helps.
