The third power of 2 + the third power of 4 + the third power of 6 + the third power of 8 + +The third power of 100 =?

The third power of 2 + the third power of 4 + the third power of 6 + the third power of 8 + +The third power of 100 =?

Formula 1 ^ 3 + 2 ^ 3 + 3 ^ 3 +... + n ^ 3 = [n (n + 1) / 2] ^ 2
Original formula = 2 ^ 3 * (1 + 2 ^ 3 + 3 ^ 3 +... + 50 ^ 3)
=8*[50*(50+1)/2]^2
=8*(25*51)^2
