Note that $\"+root%283%2C-125%29+=+-5+\"$
\n" ); document.write( "and
\n" ); document.write( " $\"+189+=+7%2A27+\"$
\n" ); document.write( " $\"+189+=+7%2A3%5E3+\"$
\n" ); document.write( "so
\n" ); document.write( " $\"+root%283%2C189%29+=+3%2Aroot%283%2C7%29+\"$
\n" ); document.write( "also,
\n" ); document.write( " $\"+56+=+7%2A8+\"$
\n" ); document.write( " $\"+56+=+7%2A2%5E3+\"$
\n" ); document.write( " $\"+root%283%2C56%29+=+2%2Aroot%283%2C7%29+\"$
\n" ); document.write( "Now the problem becomes
