help desk: Dolciani Algebra 2
I don't follow Dolciani's statement at the top.
This equation doesn't follow from Dolciani's equation; I wrote it to see whether I would understand Dolciani's statement once I solved it.
Of course, I don't know whether I solved it. It seems to me I've got a problem with cases in which the exponent is an even number - ?
