\n" ); document.write( " $\"85000+=+125000%28x%5E3%29\"$

\n" ); document.write( " $\"x%5E3+=+85000%2F125000+=+17%2F25+=+0.68\"$
\n" ); document.write( " $\"x+=+%280.68%29%5E%281%2F3%29\"$

\n" ); document.write( "To several decimal places, that is 0.879366.

\n" ); document.write( "To check that, confirm that

\n" ); document.write( " $\"125000%28.879366%5E3%29+=+85000\"$
