\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"2%2Aroot%283%2C8%2A2%29-4%2Aroot%283%2C54%29\" Factor 16 to get \"8%2A2\". Note: 8 is a perfect cube.\r

\n" ); document.write( "\n" ); document.write( "\"2%2Aroot%283%2C8%2A2%29-4%2Aroot%283%2C27%2A2%29\" Factor 54 to get \"27%2A2\". Note: 27 is a perfect cube.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"2%2Aroot%283%2C8%29%2Aroot%283%2C2%29-4%2Aroot%283%2C27%29%2Aroot%283%2C2%29\" Break up the roots.\r
