$\"%28-m%29%5E%282%2F3%29\"$ can be either\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"%28%28-m%29%5E2%29%5E%281%2F3%29\"$ or $\"%28%28-m%29%5E%281%2F3%29%29%5E2\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "These are the same thing. eg $\"%2827%29%5E%282%2F3%29\"$ can be either $\"%28%2827%29%5E2%29%5E%281%2F3%29\"$ or $\"%28%2827%29%5E%281%2F3%29%29%5E2\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Sometimes the first is easier to work out and sometimes the second version. This example... $\"%28%2827%29%5E%281%2F3%29%29%5E2\"$ is the better since $\"%2827%29%5E%281%2F3%29\"$ is 3.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So we then have $\"3%5E2\"$ which is 9.\r
\n" ); document.write( "
