RadicalBox
RadicalBox[x,n]
is a low-level box construct that represents the displayed object 
in notebook expressions.
Details and Options
- Inside \(…\) RadicalBox[x,n] can be input as \@x\%n.
- In a notebook a RadicalBox can be created using
or 
, then using 
to move to the index position. 
moves out of the radical. - The following options can be given:
-
BaseStyle {} the style to use ExponentPosition {0.2,0.1} where to place the radical exponent MultilineFunction Automatic how to handle scripts so long that line-breaking may be necessary SurdForm False whether the radical represents a Surd expression - In StandardForm and InputForm, RadicalBox[x,n] is by default interpreted on input as x^(1/n).
- In StandardForm and InputForm, RadicalBox[x,n] is interpreted on input as Surd[x,n] if the option SurdFormTrue is set.
- The baseline of RadicalBox[x,n] is taken to be the baseline of x.
- If RadicalBox[x,n] does not fit on a single line, it is output as x^(1/n).
- In StandardForm, explicit RadicalBox objects are output literally. You can use DisplayForm to see the display form of such objects.

A RadicalBox form is typically interpreted as a fractional power:
The TraditionalForm formatting for an

This radical box has the option SurdFormTrue set:
The presence of the option SurdForm ensures the boxes are interpreted in the same manner:
