I am writing a scientific notation problem the 34,500,000,000 and 72,500,000,000 my answer is 34.5x10^10 and 72.5x10^10 am I on the right track?
\n" ); document.write( "------------------
\n" ); document.write( "You're one notch to the right of the track.
\n" ); document.write( "34,500,000,000 = 3.45*10^10
\n" ); document.write( "72,500,000,000 = 7.25*10^10
\n" ); document.write( "---------------
\n" ); document.write( "There's always one digit left of the decimal point.
\n" ); document.write( "Another notation is often used:
\n" ); document.write( "34,500,000,000 = 3.45*10^10 = 3.45E10
\n" ); document.write( "72,500,000,000 = 7.25*10^10 = 7.25E10
\n" ); document.write( "It's common in computer programming, and it's easier to type and say. \n" ); document.write( "

\n" );
