Then there’s other notations:
x*3^4
And JavaScript
x*3**4
But also there’s APL:
('Marquise' 'Imperial' 'Flawless Imperial' 'Royal' 'Flawless Royal'){⍉3 ⍵⍴⍺,(⍳⍵),(3*¯1+⍳⍵)}5
Which gives
Marquise 1 1
Imperial 2 3
Flawless Imperial 3 9
Royal 4 27
Flawless Royal 5 81
Edit: I went and installed Dyalog APL (with my ten year old, valid serial number!) and all the keyboards on my new laptop just to make this post.
