I don't know which buttons I have to click or what key combination to type to calculate a cube root.

The n-th root is calculated when you put a subscript number before the square root sign.

₃√27

To enter subscript numbers with the keyboard hold down Alt while entering the number.

E.g.

  1. Go to Advanced mode
  2. Press Alt while typing 3
  3. Press

and so on

  • Also you can open a bug report for add a button of n-th root. – Helio Mar 20 '15 at 12:21

    X^(1/3) will do the same – Jean-Marie Mar 20 '15 at 13:25

    @Helio That would be a feature request, not a bug report ;) – Registered User Mar 20 '15 at 18:40
