What is the exact answer and decimal rounded to two places?
\n" ); document.write( "ln(x) + ln(x+2) = 4
\n" ); document.write( "Adding logs --> multiplication
\n" ); document.write( "ln(x*(x+2)) = 4
\n" ); document.write( "x*(x+2) = e^4
\n" ); document.write( "\"x%5E2+%2B+2x+-+e%5E4+=+0\"
\n" ); document.write( "x = -1 ± sqrt(1 + e^4)
\n" ); document.write( "------------
\n" ); document.write( "x =~ - 8.46, 6.46\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
