\n" ); document.write( "ln(8x) = 5
\n" ); document.write( "use definition of logarithm
\n" ); document.write( "8x = e^5
\n" ); document.write( "note that e is 2.718281828
\n" ); document.write( "8x = (2.718281828)^5
\n" ); document.write( "8x = 148.413158977
\n" ); document.write( "x = 18.551644872 \n" ); document.write( "
