You can put this solution on YOUR website!
ln(4x)=3
\n" ); document.write( "----
\n" ); document.write( "4x = 10^3
\n" ); document.write( "4x = 1000
\n" ); document.write( "x = 250
\n" ); document.write( "----------------\r
\n" ); document.write( "\n" ); document.write( "4+5e^(-x)=0
\n" ); document.write( "5e^(-x) = -4
\n" ); document.write( "e^(-x) = -4/5
\n" ); document.write( "----
\n" ); document.write( "No solution because no power of \"e\" can be negative.
