Which numbers between 40 and 49 have 2 and 3 in their prime factorization?Use exponents to write the prime factorization of each number.

If it has 2 AND 3 in the prime factorization, it means that the number must be divisible by 2 AND by 3, which means that it is divisible by 6.
The number(s) between 50 and 59 that are divisable by 6 would be 54. The prime factorization of 54 is
54
=6*9
=2*3*3*3
=2^{1}3^{3}
You can attempt numbers between 40 and 49 in a similar way.
