What is the prime factorization of 72?
O2-2-3-3-3
O2-2-2-3.3
O2-2-2-3
O2-2-2-5

Answer:
2 * 2 * 2*3*3
Step-by-step explanation:
To get the prime factorization of 72, break 72 down into primes
72 = 9*8
Both 9 and 8 are not prime, so break 9 and 8 down
= 3*3 * 4*2
4 is not prime so break 4 down
= 3 * 3 * 2 * 2 * 2
