Question: series with variable exponent

<p>Hi,</p>
<p>I'm a new Maple user. I'm trying to do something like this:</p>
<p><img src="file:///C:/DOCUME~1/mike/LOCALS~1/Temp/moz-screenshot.jpg" alt="" /><img src="file:///C:/DOCUME~1/mike/LOCALS~1/Temp/moz-screenshot-1.jpg" alt="" /><img src="file:///C:/DOCUME~1/mike/LOCALS~1/Temp/moz-screenshot-2.jpg" alt="" /><img src="file:///C:/DOCUME~1/mike/LOCALS~1/Temp/moz-screenshot-3.jpg" alt="" /><img src="file:///C:/DOCUME~1/mike/LOCALS~1/Temp/moz-screenshot-4.jpg" alt="" />assume(n,'integer'):series(x^n*exp(x),x);</p>
<p>and Maple complains. I eventually want to use seriestodiffeq with the result (not this exact expression - this is just an example), but I can't because of the error. Is there another way of doing this? Any help is appreciated. Thanks!</p>
