Our answer will be \"5.874+%2A+10%5En\".
\n" ); document.write( "We need to find the number that n should be.
\n" ); document.write( "Let's look at our number 58740.
\n" ); document.write( "Certainly 5874 * 10 = 58740
\n" ); document.write( "Also 587.4 * 100 = 58740
\n" ); document.write( "This is the same as \"587.4+%2A10%5E2\" = 58740
\n" ); document.write( "58.74 * 1000 = 58740
\n" ); document.write( "or
\n" ); document.write( "\"58.74+%2A+10%5E3+=+58740\"
\n" ); document.write( "5.874 * 10000 = 58740
\n" ); document.write( "or
\n" ); document.write( "\"5.874+%2A+10%5E4\"
\n" ); document.write( "Notice that if begin at the right side of 58740
\n" ); document.write( "and count the number of positions until we end up
\n" ); document.write( "between the 5 and 8 we will have moved 4 positions.
\n" ); document.write( "This leads to our answer \"5.874+%2A+10%5E4\"
\n" ); document.write( "Looking at another problem, suppose
\n" ); document.write( "we want 78,123,000,000 in scientific notation.
\n" ); document.write( "Start at the right and count till we are between the 7 and 8.
\n" ); document.write( "The count is 10, so
\n" ); document.write( "78,123,000,000 = \"7.8123%2A10%5E10\"
\n" ); document.write( "Please let me know if this is clear.
\n" ); document.write( "
\n" );
