The challenge this week is as follows: given a value in A2, where A2 is an integer and 2<=A2<=100, a formula to be entered into B2 such that, if the value in A2 is a prime number, return "Prime"; otherwise, return a string representing the prime factorisation of that number, using the full notation as given in the below examples (where a lower-case "x" is used to denote multiplication).

For those not sure of any results, I have given a full list in the attached here.

Solution next week. Best of luck!
