Question

Find the prime factorazation of 18

Answer 1

18=9x2=3x3x2 so the prime factorization is 2 x 3 x 3

Answer 2

Hello from MrBillDoesMath!

Answer:

Prime factorization: 18 = 2 * 3^2

Discussion:

18 = 9 *2 (every even number is divisible by 2)

= (3*3) *2 (as 9 = 3*3)

= 2 * 3^2

2, 3 are primes so 2 * 3^2 is the prime factorization

Thank you,
