You use Typography.Variants:
<TextBlock>
<Run>Normal Text</Run>
<Run Typography.Variants="Superscript">Superscript Text</Run>
<Run Typography.Variants="Subscript">Subscript Text</Run>
</TextBlock>

You can use something like <TextBlock>5x<Run BaselineAlignment="Superscript">4</Run> + 4</TextBlock>.
你可以使用类似的东西<TextBlock>5x<Run BaselineAlignment="Superscript">4</Run> + 4</TextBlock>。
However, as far as I know, you will have to reduce the font-size yourself.
但是，据我所知，您必须自己减小字体大小。

It's interesting to note that for some characters (m2, m3, etc) a superscript is not needed, but the unicode character can be used. For example:
有趣的是，对于某些字符（m 2、m 3等），不需要上标，但可以使用 unicode 字符。例如：
<Run Text=" m³" />
This would show m3.
这将显示 m 3。

I used a layout transform, because Typography.Variantsoften doesn't work:
我使用了布局转换，因为Typography.Variants通常不起作用：
<TextBlock Text="MyAmazingProduct"/>
<TextBlock Text="TM">
<TextBlock.LayoutTransform>
<!-- Typography.Variants="Superscript" didn't work -->
<TransformGroup>
<ScaleTransform ScaleX=".75" ScaleY=".75"/>
<TranslateTransform Y="-5"/>
</TransformGroup>
</TextBlock.LayoutTransform>
</TextBlock>
<TextBlock Text="{Binding Path=Version, StringFormat={} v{0}}"/>
The advantage of using a LayoutTransformis that it is insensitive to the fontsize. If the fontsize is changed afterwards, this superscript works where explicit FontSize setting breaks.
使用 a 的优点LayoutTransform是它对字体大小不敏感。如果随后更改了 fontsize，则此上标在显式 FontSize 设置中断的地方起作用。

I don't know if you need this to work with FormattedText specifically, or you mean derivations of Inline, but the following will work on Inlines, even if Typography.Variants="Superscript" fails to work.
我不知道您是否需要它专门用于 FormattedText ，或者您的意思是 Inline 的派生，但即使 Typography.Variants="Superscript" 无法工作，以下内容也适用于内联。
TextRange selection = new TextRange(document.ContentStart, document.ContentEnd);
selection.ApplyPropertyValue(Inline.BaselineAlignmentProperty, BaselineAlignment.Superscript);
Hope it helps!
希望能帮助到你！

Typography.Variants works only for open type fonts. If you dont like your superscripts/subscripts going outside the height of actual text then you can use something like the following:
Typography.Variants 仅适用于开放式字体。如果您不喜欢上标/下标超出实际文本的高度，那么您可以使用以下内容：
<StackPanel Orientation="Horizontal">
<TextBlock FontSize="10" Margin="0,5,0,0">1</TextBlock>
<TextBlock FontSize="30">H</TextBlock>
<TextBlock FontSize="10" Margin="0,20,0,0">2</TextBlock>
</StackPanel>

This is the only thing that worked for me. It also gives you more control over the alignment and font size.
这是唯一对我有用的东西。它还使您可以更好地控制对齐方式和字体大小。
<TextBlock Grid.Row="17">
3 x 3<Run FontSize="6pt" BaselineAlignment="TextTop">2</Run>)
</TextBlock>

Setting for superscript works fine with the following code:
使用以下代码设置上标可以正常工作：
<TextBlock Text="(cm" />
<TextBlock ><Span BaselineAlignment="Top" FontSize="8">2</Span></TextBlock>
<TextBlock Text=")" />
Setting the Baseallignment for subscript in the Span tag did not work for me. I tried the following code and it worked fine.
在 Span 标签中为下标设置 Baseallignment 对我不起作用。我尝试了以下代码，效果很好。
<TextBlock Text="H" />
<TextBlock Text="2" Margin="-2,0,-2,0" TextBlock.LineHeight="3" >
<TextBlock Text="O" />
