    Objective: Apply exponents using Scientific Notation



     Let's start off by reading some articles about planets!
         *Write down interesting mathematical facts from the article.




       Daily Question: Write 206,000,000 in scientific notation.
                                   -3
                       Write 4.1x10 in standard form.
                                                                                                   These numbers are HUGE!!! And it is hard to tell right away the specific
                                                                                                   size of the number... so we use scientific notaiton to help us out!




    Scientific notation- a type of short hand notation to write out really big numbers             Convert the following numbers into scientific notation:

                                                                                                  32,300,000,000                                   0.0000000006
              rules: comes in the form of         # x 10#


    from notes yesterday: 103 =                                                                                                                    0.0000000204
                                                                                                  710,200,000,000


                                     4.2 x 108                                                                                                     0.0000109
                                                                                                  10,200,000,000
                                                         so all we have to do is move our
                                                         decimal around... and we move it
                                                         however many place the exponent tells
                                                         us to.
                                                                                                                                                   0.00043

     1.093 x 1023                                                 7.55 x 10-11                   8,000,000,000

    Standard Form- long hand notation; does not contain exponents.
                                                                     Convert the following numbers into standard form:
      "normal" numbers... like
