11.03 Scientific Notation 

Learning
Outcomes: The student will:
Change a number to scientific notation 
843 000 000 = 8.43 x
10^{8} 843 000 = 8.43
x 10^{5}
843 = 8.43 x 10^{2}
84.3 = 8.43 x 10^{1}
8.43 = 8.43 x 10^{0} 
Scientific notation is a product
of a number between 1 and 10 and a power of
10. 
Change scientific notation to a number 
5.69 x 10^{0} = 5.69 5.69 x 10^{1} = 56.9
5.69 x 10^{2} = 569
5.69 x 10^{3} = 5690
5.69 x 10^{4} = 56 900 
Scientific notation is a product of a number between 1 and 10 and a power
of 10. 

Review:
Scientific notation has the following
form:
N X 10^{x}
where N is a number greater than
1 but less than 10 and
^{x} is an
exponent of 10.
Scientific notation is a convenient way of writing very large or very
small numbers:
