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

2,140,000,000                   1.8203 x 107                   1.8 x 10-6

8 x 104                       9 x 10-8
103,000,000
