  $price contains all the price elements that are the first
price element within their cd parent element.  So with your
sample input, $price will contain a node-set with *two*
elements.

  math:sqrt <http://www.exslt.org/math/functions/sqrt/index.html>
takes one (and only one) number in argument.  So your error.

  It is like you want in the for-each to take the price
element of the current cd element instead:

    <xsl:for-each select="catalog/cd">
      <xsl:value-of select="price"/>
      <xsl:value-of select="math:sqrt(price)"/>
    </xsl:for-each>
