One doubleing period \"45%2F45\".
\n" ); document.write( "x minutes, \"x%2F45\";\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"y=10000%282%29%5E%28x%2F45%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "If y=60000, find x.
\n" ); document.write( "\"10000%2A2%5E%28x%2F45%29=60000\"\r
\n" ); document.write( "\n" ); document.write( "\"2%5E%28x%2F45%29=6\"\r
\n" ); document.write( "\n" ); document.write( "\"%28x%2F45%29log%28%282%29%29=log%28%286%29%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"x=45%2Alog%28%286%29%29%2Flog%28%282%29%29\", and you can use calculator or table of common logarithms.

\n" );
