You can put this solution on YOUR website!
e^-x = 3
\n" ); document.write( "ln(e^-x) = ln(3)
\n" ); document.write( "-x*ln(e) = 1.0986
\n" ); document.write( ":
\n" ); document.write( "ln of e is 1, therefore
\n" ); document.write( "-x = 1.0986
\n" ); document.write( "x = -1.0986
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check on a calc: enter e^(-(-1.0986))= 2.9999 ~ 3 \n" ); document.write( "

\n" );
