Use a factor tree, upside down method or the number squares. Write the prime factorization so that the factors are written in ascending order (from smallest to largest). Show the individual steps including your factor tree. Then enter into the answer box the prime factorization using for multiplication and for exponentiation. For example the answer to 12 is 2*2*3. Show all work using the correct method on your handwritten work/answer sheet. 39 =
