Question

The following is the prime factorization of which composite number?

22 • 32 • 5

1.20
2.60
3.120
4.180

Answer 1

The answer is 180 2^2=4 3^2=9 9×4=36 so 36×5=180

Explanation:

Answer 2

See below.

Explanation:

The prime factorization of number is the break down into factors which are prime numbers (numbers without factors except 1 and itself). The factors 22 and 32 are composite numbers since they have more than 1 and itself as factors. They are not prime.

However, the factorization of 22 * 32 * 5 will equal a number. 22*32*5 = 3, 520. But it does not match the solutions given.
