Property 1.\r
\n" ); document.write( "\n" ); document.write( "ln(x^n) = nln(x)\r
\n" ); document.write( "\n" ); document.write( "For example
\n" ); document.write( "ln(105) = 5ln(10) or ln(x^7) = 7ln(x)\r
\n" ); document.write( "\n" ); document.write( "Property 2.\r
\n" ); document.write( "\n" ); document.write( "ln(x * y) = ln(x) + ln(y)\r
\n" ); document.write( "\n" ); document.write( "Property 3.
\n" ); document.write( "ln(x/y) = ln(x) - ln(y)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Property 4.
\n" ); document.write( "ln(ex) = x\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Please be careful because
\n" ); document.write( " ln(x + y) is not = ln(x) + ln(y)
\n" ); document.write( "nor ln(x - y) is not = ln(x) - ln(y).\r
