Jan 18, 2017 at 16:56 comment added nalzok @YuvalFilmus In my understanding, "repeat" means "appear more than once" in this exercise. Both R1 and R2 appear twice in the first formula, and only once in the second one, so the second formula is "such a form that no variable that represents an uncertain number is repeated"
