Answer 1

You can do this inside of a markdown cell. A markdown cell can be created by selecting a cell then pressing the esc key followed by the M key. You can tell when you have converted a cell to markdown when In [ ]: seen to the right of the default code cell is gone. Then you can input the following code that uses latex with markdown to represent sub/super-scripts:

Latex subscript:

$x_{2}$

Latex superscript:

$x^{2}$

You can find more detailed examples here.

Note that the text must be left-justified with a blank line separating it from surrounding text. This drove me mad not working because I had indented my text by four spaces, accidentally telling markdown it was pre-formatted code. – Youthen

Doesn't work in headings unfortunately :(. At least not in Jupyter. – Rumor

Answer 2

<sup>superscript text </sup> also works, and might be better because latex formatting changes the whole line etc.

This is much better answer. Btw the subscript tag is <sub>. – Glimp

Answer 3

What a meta question! One needs to use Markdown to answer Markdown syntax questions. Markdown does have the <sup></sup> and <sub></sub> tags that will adjust text to super- or sub- script, respectively in the typeface of the current block. If you are using the scripts for mathematical statements like this the LaTeX transformation makes sense. If you are using the scripts for footnotes or perhaps for something like chemical formulas (e.g. H₂O) it might be preferable to use the first method rather than LaTeX. Mixing fonts is generally not considered a good graphics/typography practice!

Let's say, you want to write this:

Then, here is what you need to write in your Markdown:

$\hat{Y} = a + b_1 X_1 + b_2 X_2 + b_3 X_1 X_2 + b_4 X_1^2 + b_5 X_2^2$

Another example:

$\hat{Y} = \hat{\beta}_{0} + \sum \limits _{j=1} ^{p} X_{j}\hat{\beta}_{j}$

This answer should really be marked down as it doesn't work in Jupyter. Did you test it in Jupyter notebook or Jupyter Lab. It didn't work for me. – Parishioner

You would need to have a $ on both sides. I updated it. – Nolita

Answer 5

You can use HTML ' ^superscript '

You can also use Latex $foo^{superscript}$, but the font used to render the text will change and you might not like how it looks.
