2024 = 2³ + 3³ + 4³ + 5³ + 6³ + 7³ + 8³ + 9³
I just saw somebody on mastodon share this fact, and I wanted to share it here too :))
It can be explained by the follow:
2025 = 2024 + 1
2025 = 45²
45 = 1 + 2 + ... + 9
(1 + ... + n)² = 1³ + ... + n³
and since 1³ is just one, we get the above equation for 2024 :))
This also means that next year will be even nicer, as it will include the 1³ :))
Do you have any other interesting facts about 2024 ? :))
The best name I've found for the last formula is just "Sum of consecutive cubes". I had never heard about that relation before, it really is bizare how math is connected sometimes :))
