As mentioned above, all sufficiently large numbers can be written as 16 fourth powers. Assuming that the 9 cubes is optimal in this sense (i.e., there are arbitrarily large numbers requiring all 9 cubes), we get an interesting sequence 1,4,9,16.... Is this just coincidence or can every sufficiently large natural number be expressed as k^2 kth powers? (I know NOTHING about this field, just found the question interesting...) | |
