On the first round $\"5=5%5E1+\"$ people hear the joke
\n" ); document.write( "On the second round, those $\"5+\"$ people each tell $\"5+\"$ more people, so $\"5%2A5+=+25+=5%5E2\"$ people hear the joke.
\n" ); document.write( "On the third round, those $\"25\"$ people each tell $\"5\"$ more people, so $\"25%2A5+=+125=5%5E3\"$ people hear the joke.
\n" ); document.write( "On the fourth round, those $\"125\"$ people each tell $\"5\"$ more people, so $\"125%2A5+=+625=5%5E4+\"$ people hear the joke.
\n" ); document.write( "On the fifth round, those $\"625\"$ people each tell $\"+5+\"$ more people, so $\"+625%2A5+=+3125=5%5E5+\"$ people hear the joke.
\n" ); document.write( "On the sixth round, those $\"3125\"$ people each tell $\"5\"$ more people, so $\"3125%2A5+=+15625=5%5E6\"$ people hear the joke.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "expression $\"5%5E6\"$ shows the number of people that will hear the joke after the sixth round\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "general formula:\r
\n" ); document.write( "\n" ); document.write( " $\"y=5%5Ex\"$ where $\"x\"$ is the number of rounds and $\"y+\"$ the number of people hear the joke\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
