Answer 2

the prime factorization of 18 is 2 times 3 and 1 time two

Explanation:

Factorization refers to the process by which we decompose a number in its prime factors, in other words, we express the number as a multiplication of prime numbers.

In this case we have the number 18:

18= 9 x 2, however, 9 is not a prime number so we are going to factor the 9.

18= 3 x 3 x 2.

Now we see that all our factors are prime and thus this is the factorization of 18.

Thus, the prime factorization of 18 is 2 times 3 and 1 time two
