Total Posts: 1 | Hello, I have a TI-89 Titainium(sp?).
I have no idea of how to perform "root" problems.
For instance, what buttons would I need to press to type this into my calculator:
3 root-symbol 7
Also, what buttons would I have to press in order to type this in:
cube root-symbol 5
I just cannot seem to figure out how to do this. Thanks. |

(By y√(x), I mean that y is the root power, not a factor of an equation.)
