How do real roots work
WebIt's the same reason why there's a name for a pentagon, a hexagon, and a heptagon but no name in common knowledge for a 67-gon, for example. We only frequently deal with numbers that have an exponent of 3 and below (probably because there are only 3 spatial dimensions), so there wasn't too much of a need to make a special name for raising to the …
