document.write( "a number under 100 and above 1 that has only 5 \r\n" );
document.write( "factors.\r\n" );
document.write( "\r\n" );
document.write( "Theorem:\r\n" );
document.write( "If p is a prime number, then pn has\r\n" );
document.write( "n+1 factors\r\n" );

document.write( "So if n+1 = 5\r\n" );
document.write( "        n = 4\r\n" );
document.write( "\r\n" );
document.write( "So the 4th power of any prime number has 5 factors.  \r\n" );

document.write( "24 = 16 has 5 factors, \r\n" );
document.write( "namely, 1,2,4,8, and 16\r\n" );
document.write( "34 = 81 has 5 factors,\r\n" );
document.write( "namely, 1,3,9,27, and 81\r\n" );
document.write( "\r\n" );
document.write( "So there are two solutions, 16 and 81.\r\n" );
