Simple way to show is first:\r
\n" ); document.write( "\n" ); document.write( "3400000
\n" ); document.write( "0020000
\n" ); document.write( "____________
\n" ); document.write( "3420000\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "You want to MOVE the (implied) decimal point to the left until its placement indicates a number greater than or equal to 1 and less than 10; and then indicate the power of ten which would reverse that decimal placement.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "3.42______ happens if you move decimal point 6 places.\r
\n" ); document.write( "\n" ); document.write( "This means your power of ten must be $\"10%5E6\"$ .\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Your number converted to scientific notation is $\"highlight%283.42%2A+x%2A+10%5E6%29\"$ .
\n" ); document.write( "Please ignore the dots around the x; rendering was not working and so they were necessary for the expression to appear.
\n" ); document.write( "That does show the use of \"x\" as a multiplication symbol. \n" ); document.write( "

\n" );
