When asked to write the prime factorization of the number 27, a student wrote 9·3. explain the error and rite the correct answer. what would be the correct answer

Prime factors are numbers used to multiply to another number that cant be divided by anything else except for 1. The problem is that 9 can be divided into 3 and 3. So the prime factorization of 27 is 3 x 3 x 3

The answer is: y would equal 3 because if you simplify the equation then it would be y= 3x+9 and if you divide 3x and 9 by 3 it would equal 3. y= 3
