<p>
To get an expression, exp, to appear as a superscript, you just type
<tt>^{exp}</tt>.<p>
Can be used only in <a href="ltx-115.html#math">math</a> mode.
Thus, for a simple expression that is part of the running text:
<pre>
<tt>x$^3$ is the third power of x</tt>
</pre>
should display as "x<sup>3</sup> is the third power of x". Note that
the braces around the argument may be omitted if the superscript is
a single character.
<p>
If a symbol has both subscripts and superscripts, the order doesn't matter.
The following are equivalent:<br>
<pre> <tt>a_n^2</tt> and <tt>a^2_n</tt></pre>
<p>
Superscripts may have their own superscripts:
<pre>
<tt>$x^{y^{z}}$</tt>
</pre>
should display something like
<pre>
z
y
x
</pre>
