I presume you mean 7 x 10^(-6) instead of 7 x 10^6.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The length of the blood cells would simply be (2 x 10^13)(7 x 10^(-6))\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "= 14 x 10^7 = 1.4 x 10^8 (meters).

\n" );
