You don't find the prime factorization by using exponents, they're just a shorthand for notation once you find it. The prime factorization of 900 is 22 x 32 x 52
Find the prime factorization. Identify the distinct prime factors. Add them up.
A number is prime when it only has one and itself as factors is prime. Therefore, to tell if a number is prime or composite simply find it's factors. If it has more than two factors than it is not a prime number, it is composite.
A prime number cannot have any number multiplied to make that number, except for one. example: 9 is not prime because 3 times 3 is 9.
