$202^3 = 8.242.408 = (–8 + 242 – 40 + 8)^3$

$204 = 3^2 + 7^2 + 5^2 + 11^2 = 2^2 + 8^2 + 6^2 + 10^2$

$204^2 = 23^3 + 24^3 + 25^3 = 41.616$

$206^3 = 8.741.816 = (8 + 7 + 4 + 181 + 6)^3$

$208^3 = 8.998.912 = (08 + 99 + 89 + 12)^3$

$209 = 1^6 + 2^5 + 3^4 + 4^3 + 5^2 + 6^1$

$305^3 = 28.372.625 = (283 + 7 + 2 + 6 + 2 + 5)^3$

$88+209 = 297$ και $88.209 = 297^2$ 

$2.401 = (2 + 4 + 0 + 1)^4 = 7^4$

$10.000 = (1+2+3+4)^4 = $

$=[(1^5+2^5+3^5+4^5)+(1^7+2^7+3^7+4^7)]/2$
