It must be my three working neurons took some days (quite a few, in fact) off: I don't understand the given data:

"Cubes" (I suppose integer numbers which are cubes of other integers, like 8, 27, 64 and etc.), "whose base numbers

exponents"...what exponents? Of whom or what? For example, with , are we talking of 3 (the exponent of 4)? That seems

to be a triviality, since all the numbers are cubes.
