@CrazyCountryGirl - How will you write 5,500 in the scientific notation? (I am just making sure that you know about scientific notation)

Actually would you be willing to check 12 question like these? Please? I promise it's not homework or anything. I'm doing one more test next week. I'm trying to study and make sure I know it by checking my answers. :)
