Power Functions and Power Root Functions
Note that the input methods for ,
,
, and
are different depending upon whether you are using Natural Display or Linear Display.

Note
The following functions cannot be input in consecutive sequence: x2, x3, , x-1. If you input 2
, for example, the final
will be ignored. To input 222 , input 2
, press the
key, and then press
(MthIO-MathO).
