<PRE><B>Question 381226</B>
&lt;br&gt;&lt;font face=&quot;Tahoma&quot;&gt;{{{(5^2)^(-9)}}} &lt;br&gt;

{{{5^(-18)}}}&lt;br&gt;

{{{1/(5^18)}}}&lt;br&gt;

or you can simplify a little easier by simplifying {{{5^2}}} first:&lt;br&gt;

{{{(5^2)^(-9)}}}&lt;br&gt;

{{{25^(-9)}}}&lt;br&gt;

{{{1/(25^9)}}}&lt;br&gt;

The second version is probably the better answer.&lt;br&gt;

I hope this helps!&lt;br&gt;</PRE>
