:
\n" ); document.write( "We can write it:
\n" ); document.write( "\"%28%289-sqrt%28108%29%29%29%2F3\"
\n" ); document.write( ":
\n" ); document.write( "the perfects squares that are factors of 108
\n" ); document.write( "\"%28%289-sqrt%284%2A9%2A3%29%29%29%2F3\"
\n" ); document.write( ":
\n" ); document.write( "Extract the squares
\n" ); document.write( "\"%28%289-2%2A3%2Asqrt%283%29%29%29%2F3\"
\n" ); document.write( "which is
\n" ); document.write( "\"%28%289-6%2Asqrt%283%29%29%29%2F3\"
\n" ); document.write( "Same as:
\n" ); document.write( "\"9%2F3\" - \"%28%286%2Asqrt%283%29%29%29%2F3\"
\n" ); document.write( "Cancel the 3's and you have:
\n" ); document.write( "3 - \"2%2Asqrt%283%29\"
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Do much the same thing here:
\n" ); document.write( "\"%28%286-sqrt%2820%29%29%29%2F2\"
\n" ); document.write( ":
\n" ); document.write( "\"%28%286-sqrt%284%2A5%29%29%29%2F2\"
\n" ); document.write( ":
\n" ); document.write( "\"%28%286-2%2Asqrt%285%29%29%29%2F2\"
\n" ); document.write( ":
\n" ); document.write( "The 2 divides into 6 and 2 leaving you with:
\n" ); document.write( "3 - \"sqrt%285%29\"
\n" ); document.write( " \n" ); document.write( "
