2025 is mathematically fascinating

Some interesting mathematical facts of the year, that we are approaching, 2025:

1: 2025, itself is a square,  viz. 452 = 2025

2: It’s a product of two squares,  viz. 9² x 5² = 2025

3: It’s the sum of three squares, viz. 40²+ 20²+5² = 2025

4: It’s the sum of cubes, of all the single digits, from 1 to 9 = viz. 1³+2³+……9³ = 2025.

Much of the magic comes because of the presence of number 9. Remember also Kaprekar’s constant 6174. https://en.wikipedia.org/wiki/6174

    it’s really Great. Hope our Godhood and love to the Almughy and Nation and world be in such multiple squares and cubes

    Yes..it is mathematically fascinating.. Hoping it will be so in its magical events to resolve the world conflicts.

    your pyramidal 1 numbers is interesting: whenever the One (Divine) is multiplying Itself, there is no place for a zero 😉

      Yet the Divine managed to create the zero, cypher, shunya, void, nothingness, this for the creative delight of becoming many; He emptied himself out so that he could manifest, (many-fest). He was alone and He called his creative Force to do it.

      The Absolute, the Perfect, the Alone

      Has called out of the Silence his mute Force

      Where she lay in the featureless and formless hush

      Guarding from Time by her immobile sleep

      The ineffable puissance of his solitude. ||15.7|| …

    A comment has come which says that, after

    1936 = 11x11x4x4 = 44×44

    we have

    2025 = 9x9x5x5 = 45×45.

    So the next will be

    2116 = 23x23x2x2 = 46×46

    Also a number that can be divided by only 2 primes.

    Completion of 2025 will mark the completion of exactly a fourth of this century, a good enough data size to look back a few years later and contemplate how the first quarter of the century compares to the then ‘present’.

    Points 1, 2 and 4 are related. I can show that

    S_3 (n) = 1^3+2^3+…..+n^3 = [S_1(n)]^2

    where S_1(n) is the sum of integers from 1 to n (=n[n+1]/2], S_2(n) is the sum of squares of integers upto n, which incidentally is n(n+1)(2n+1)/6, and S_3(n) is sum the of cubes of integers upto n. 

    So S_3(9)=[9×10/2]^2

    =9^2 × 5^2

    =45^2=(40+5)^2

    =40^2+10×40+5^2

    =40^2+20^2+5^2

    =2025
