this is because when thinking about scientific notation you know that you have to include a decimial and how many times you are moving it and whether it is a negative of a positive.
this means that you would take 5600 and you would put the decimal inbetween 5 and 6 because they are significant numbers and then you would have to figure out how many places to the right you need to go inorder to make it 5600
meaning you have to move it three times therefore it becomes
5.6 * 10^3
