solve the exponential equation
\n" ); document.write( "2^(x+1)=5^(1-2x)
\n" ); document.write( "---
\n" ); document.write( "(x+1)*log(2) = (1-2x)*log(5)
\n" ); document.write( "----
\n" ); document.write( "x[log(2)+2log(5)] = log(5)-log(2)
\n" ); document.write( "---
\n" ); document.write( "x[1.6990] = 0.3979
\n" ); document.write( "---
\n" ); document.write( "x = 0.2342..
