In Chapter 1, you learned about factors and about prime numbers. It is sometimes useful to represent a number as the product of all of its prime factors. For example, the number 200**factored** into primes.

For example,

We can then use **exponents** to write repeated multiplication, showing that the prime factorization of

Write the prime factorization of each of the numbers below. Use exponents to represent repeated multiplication.

Separate the number into all of its primes.

Use exponents to simplify the repeated multiplication.

Follow the steps outlined in part (a). Remember to use exponents!
