\n" ); document.write( " $\"log%28x%29-3log%28y%29+=+1\"$
\n" ); document.write( " $\"log%28x%2Fy%5E3%29+=+log%2810%29\"$
\n" ); document.write( " $\"x%2Fy%5E3+=+10\"$
\n" ); document.write( " $\"x+=+10y%5E3\"$
\n" ); document.write( " $\"xy+=+10y%5E4+=+160\"$
\n" ); document.write( " $\"y%5E4+=+16\"$
\n" ); document.write( " $\"y+=+2\"$

\n" ); document.write( "We need to choose the positive 4th root of 16, because the log of a negative number is undefined.

\n" ); document.write( "y = 2; x = 80 \n" ); document.write( "
