You can put this solution on YOUR website!
The first rule for scientific notation is that the number (significant figure) has to be between 1 and 10
\n" ); document.write( "So, your first number must be \"4.09\"
\n" ); document.write( "Then, you add the traditional \"10%5Ex\"
\n" ); document.write( "Then count how many spaces to the right you moved the decimal. (4)
\n" ); document.write( "Since you moved it to the right, your exponent after the 10 will be negative 4
\n" ); document.write( "So, your answer in scientific notation is \"4.09%2A10%5E-4\"
\n" ); document.write( "Hope this helps!
