I've been trying to find how to get a cube root - all I can find is:

sqrt EXPR - This function returns the square root of EXPR. If EXPR is omitted, it returns the square root of $_. For other roots such as cube roots, you can use the ** operator to raise something to a fractional power.

which is great, except that I don't know what it means!
