  Prime Factorization: A number written as the 
   product of its prime factors.
  Exponent: Tells how many times a number 
   (the base) is used as a factor.
    You can use factors to write a number in 
                 different ways.
         Factorization of 12
                                        Notice that 
      1 • 12   2 • 6  3 • 4 3 • 2 • 2   these factors 
                                        are all prime.
         What do you notice about how the 
           last set of factors are written?
           The prime 
       factorization of a 
     number is the number 
     written as the product 
      of its prime factors.
   What is an exponent?
   What is an exponent?
    An exponent tells how many times 
    a number called the base is used 
    as a factor.
   A number is in exponential form 
   when it is written with a base and 
   an exponent.
