Which expression shows the prime factorization of 36?

a2 × 2 × 3

b2 × 3 × 3

c2 × 2 × 2 × 3 × 3

d2 × 2 × 3 × 3

36we need to break this down...12 * 3 = 36
12 * 3we can break this down because 12 is not prime...4 * 3 = 12
4 * 3 * 3...we can break the 4 down because it is not prime
2 * 2 * 3 * 3 < prime factorization
