In 1999 the GDP in billions will be:
\n" ); document.write( " $\"+%28+577+%2B+.032%2A577+%29%5E14+\"$
\n" ); document.write( " $\"+577%2A1.032%5E14+\"$
\n" ); document.write( " $\"+577%2A1.5542+=+896.792+\"$
\n" ); document.write( "-------------------------
\n" ); document.write( "Note that $2.8 trillion = $\"+2800+\"$ billion
\n" ); document.write( "I can say that in the year 1985 + $\"+n+\"$ ,
\n" ); document.write( "GDP in billions = $\"+2800+\"$
\n" ); document.write( " $\"+2800+=+577%2A1.032%5En+\"$
\n" ); document.write( " $\"+1.032%5En+=+2800%2F577+\"$
\n" ); document.write( " $\"+1.032%5En+=+4.8527+\"$
\n" ); document.write( "Take the log of both sides
\n" ); document.write( " $\"+n%2Alog%28+1.032+%29+=+log%28+4.8527+%29+\"$
\n" ); document.write( " $\"+.01368n+=+.68598+\"$
\n" ); document.write( " $\"+n+=+50.1447+\"$
\n" ); document.write( "1985 + 50 = 2035
\n" ); document.write( "In 2035 the GDP was $2.8 trillion
\n" ); document.write( "Hope I got it! \n" ); document.write( "

\n" );
