You can put this solution on YOUR website!
With scientific notation, you should always
\n" ); document.write( "end up with a number that looks like this:
\n" ); document.write( "a.aaa x $\"10%5Eb\"$
\n" ); document.write( " $\"+%281.6%2A10%5E4%29%2A%289.9%2A10%5E6%29+\"$
\n" ); document.write( " $\"+1.6%2A9.9%2A10%5E4%2A10%5E6+\"$ ( just regrouping the 4 factors)
\n" ); document.write( " $\"+15.84%2A10%5E10+\"$ (add the exponents)
\n" ); document.write( "Now you want $\"1.584\"$ instead of $\"+15.84+\"$ , so
\n" ); document.write( "use this conversion:
\n" ); document.write( " $\"+15.84+=+1.584%2A10%5E1+\"$
\n" ); document.write( "Now you have
\n" ); document.write( " $\"+1.584%2A10%5E1%2A10%5E10+\"$
\n" ); document.write( " $\"+1.584%2A10%5E11+\"$ (add the exponents again)
\n" ); document.write( " \n" ); document.write( "

\n" );
