This is an example of the following rule:
\n" ); document.write( " $\"%28a%5Eb%29%5Ec+=+a%5E%28b%2Ac%29\"$
\n" ); document.write( "This is easily demonstrated.
\n" ); document.write( "Suppose $\"a=3\"$ , $\"b=4\"$ , $\"c=5\"$ , then
\n" ); document.write( " $\"%28a%5Eb%29%5Ec+=+a%5E%28b%2Ac%29\"$
\n" ); document.write( " $\"%283%5E4%29%5E5+=+3%5E%284%2A5%29\"$
\n" ); document.write( " $\"%283%5E4%29%5E5+=+%283%5E4%29%2A%283%5E4%29%2A%283%5E4%29%2A%283%5E4%29%2A%283%5E4%29\"$
\n" ); document.write( " $\"3%5E4+=+3%2A3%2A3%2A3\"$
\n" ); document.write( "

\n" ); document.write( "This is the same as $\"3%5E20+=+3%5E%284%2A5%29\"$
\n" ); document.write( "The problem is
\n" ); document.write( " $\"P%28%281+%2B+r%29%5E2%29%5E3+=+P%281+%2B+r%29%5E6\"$ which I just showed
\n" ); document.write( "is true by analogy \n" ); document.write( "

\n" );
