Show HN: 2025 = sum(I^3) for I = 0..9

This year's number is kinda fun:<p>2025 = 0^3 + 1^3 + 2^3 + 3^3 + 4^3 + 5^3 + 6^3 + 7^3 + 8^3 + 9^3<p>Which is equivalent to:<p>2025 = (0 + 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9) ^ 2 = 45 ^ 2<p>Next time this will happen is 1000 years from now, in 3025. See y'all then!

If we go with 45 ^ 2 then 46 ^ 2 = 2116 is a bit closer than 3025.

haha! I knew it was a perfect square but I did not know the sum thing, interesting!
