Integermania! - First Four Composites

The first four composite numbers are 4, 6, 8, and 9.  Create each of the positive integers using one copy of each number, and any standard operations.  All four numbers must be used, but no others.  Your solutions will be assigned an exquisiteness level.

Use the online submissions page to get your Integermania solutions posted here!  Five "new" or "improved" solutions per person per month are accepted.

Note:  If the math symbols are not displaying correctly, you need to upgrade your browser to either IE 6.0 or Netscape 6.0 or better.  This page will print nicely using the "shrink to fit" option in Netscape, with landscape orientation and narrow margins.
