# Nice looking double superscript

How can I make a nice look double superscript like the picture which was made in MS Word?

{R}^e{^{\mathbf{Tx}}}


• You really would need to define "nice" from your point of view, or - better even - give an example why you don't like the default LaTeX method R^{e^{\mathbf{Tx}}}. Also: Maybe related to Inverse tensor with indices – Timm Mar 16 '17 at 12:38
• One { is misplaced. I would also replace \mathbf with \boldsymbol from amsmath. Try R^{e^{\boldsymbol{Tx}}}. This is much better than MS Word:-) – StefanH Mar 16 '17 at 12:39

Is the Tx in the image really bolder that the R?

It doesn't look that way but hard to tell from a low resolution image. Certainly it is in italic so you do not want \mathbf either nothing at all or \bm{Tx} if you really need bold Tx.

You also have the ^ in the wrong place: the superscript is on the e so e^{Tx} not e{^{Tx}} (which puts the superscript on an empty base to the right of the e).

so

R^{e^{Tx}}


or with bm package

R^{e^{\bm{Tx}}}

• I am sorry. I misplace ^. It worked. – OOzy Pal Mar 16 '17 at 13:07
