Keltham will throw some more logarithms examples! Dath ilani kids, before they run into logarithms, have prior experience with seeing numbers as bags of prime factors, maybe running over that for a few minutes will help with priming this pump.
15 is a bag of a 3 and a 5.
4 is a bag of two 2s.
15*4 = 60, so 60 is a bag of two 2s, a 3, and a 5.
If you multiply 2 and 3, you get 6.
So if you divide 60 by 6, you should get a bag of one 2 and a 5.
2 times 5 is 10. Checks out, right?
