But the latter would be "3 to the x power", whereas the former is "x to the 3 power", so I think "Three Power" means "x^3". + This is also corroborated by Example #2, which states that 0 is a "Three Power" because "0 = 0^3", not "0 = 3^0" which is false (3^0 = 1). So this problem boils down to "Given an integer x, does there exist an integer r such that r^3 = x?" |
