Question

How do I graph a fifth-root power function on an Nspire?

Answer 1

Begin by opening up a new document, and selecting the Graphs application.
Type `f1(x) = root(5)(x)` and press Enter.

An additional way to enter this function is to use `x^frac{1}{5}` instead.

Here, you can see that both ways lead to the correct graph:
