ETA: Nevermind, I have no idea what she's talking about since she already mentioned the quare root of 9 being 3.
What do you mean by 'cubed' nisaba?
I THINK, but do not presume to know, that perhaps she meant...
9^3 = 729
if you add up all the numbers = 729 = 18 = 9
So when cubed, 9 goes back to 9, so to speak.
