SqrtBox

FilledSmallSquareSqrtBox[x] represents in input and output.

FilledSmallSquare Inside \( ... \) SqrtBox[x] can be input as \@ x.

FilledSmallSquare In a notebook a SqrtBox can be created using ControlKeyLeftModified2RightModified or ControlKeyLeftModified@RightModified. ControlKeyLeftModifiedRightModified moves out from under the square root sign.

FilledSmallSquare In StandardForm and InputForm, SqrtBox[x] is interpreted on input as Sqrt[x].

FilledSmallSquare The baseline of SqrtBox[x] is taken to be the baseline of x.

FilledSmallSquare If SqrtBox[x] does not fit on a single line, it is output as x^(1/2).

FilledSmallSquare In StandardForm, explicit SqrtBox objects are output literally. You can use DisplayForm to see the display form of such objects.

FilledSmallSquare See The Mathematica Book: Section 2.8.10.
