Find the prime factorization of 75.  Write your answer using exponential notation.
PRIME                 NOT PRIME
2,3,5,7,11                4,6,8,9,10                 =75

For Example: 3*5*5=75
Good Luck...
There are some ways to do factorization:
First, you have to do factor tree. Write the number, and write the first two factors of the number, and expand it until it's a prime number.

Secondly, you can list down all of the factors of it; but it's a long process.

Lastly, you can divide it by the least prime number.
