You can put this solution on YOUR website!
Let's use a property of directly proportional values:\r
\n" ); document.write( "\n" ); document.write( "\"sqrt%286%29%2F2+=+sqrt%28x%29%2F1\"
\n" ); document.write( "\"sqrt%28x%29+=+sqrt%286%29%2F2\"
\n" ); document.write( "\"x+=+6%2F4\"\r
\n" ); document.write( "\n" ); document.write( "
\n" ); document.write( "
\n" );
