<PRE><B>Question 937440</B>

How do I simplify the following expression, with my answer having positive exponents?
9^-1 9^1/2
&lt;pre&gt;&lt;font face = &quot;Tohoma&quot; size = 4 color = &quot;indigo&quot;&gt;&lt;b&gt;If 9&lt;sup&gt;(-1)&lt;/sup&gt; * 9&lt;sup&gt;1/2&lt;/sup&gt;, then we get: 9&lt;sup&gt;(-1 + 1/2)&lt;/sup&gt;______9&lt;sup&gt;-1/2&lt;/sup&gt;_____{{{1/9^(1/2)}}}, or {{{1/sqrt(9)}}}, or {{{highlight_green(1/3)}}}  
You can do the check!!
