There are two ways to why the prime factorization for 45 equals 3x3x5. First of all, you may start with multiplying it. Start with 3x3; which equals nine or 9. Then 9x5 equals 45. the other way is that you may break it down, starting from 45. first you find 2 factors that you can multiply to receive the answer or product of 45. If you said 9x5 you are correct. So therefore you below the number 45 you may write the equation 9x5. Then you check if any of the numbers can be reduced or simplified. Let's start with the 5: can you find any factors of five? No, so you bring down the 5. How about 9? Yes, 3x3. Are there any others? No, there are no others, unless you include 9x1. But that's too easy. Below the 9 and beside the 5 write the multiplication sign, then 3x3. It should look something like this:
4 5
^
9 x 5
^ ^
3 x 3 x 5

how do i get the prime factorization of 45
Ronald writes the prime factorization of 90 as 2x3x3x5 on the board Donald write the prime factorization of 90 as 3²x5 Who is correct?
Ronald is correct, as 2x3x3x5 = 6x3x5 = 18x5 = 90. Ronald would have also been correct to put 2x32x5. Donald is incorrect, as 32x5 = 3x3x5 = 9x5 = 45.
