Rule 1: $\"log%28b%2C%28x%5En%29%29=n%2Alog%28b%2C%28x%29%29\"$ , so $\"ln%28e%5E4%29=4%2Aln%28e%29\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Rule 2: $\"log%28b%2C%28b%29%29=1\"$ . Since $\"ln%28x%29\"$ is the same thing as $\"log%28e%2C%28x%29%29\"$ , $\"ln%28e%29=1\"$ .\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Putting it all together:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"ln%28e%5E4%29=4%2Aln%28e%29=4%2A1=4\"$ \n" ); document.write( "

\n" );
