1^3+2^3+3^3+… +What is (n-1) ^ 3 + n ^ 3 equal to?

1^3+2^3+3^3+… +What is (n-1) ^ 3 + n ^ 3 equal to?

Using mathematical induction. S1 = 1 ^ 3 = 1 ^ 2s2 = 1 ^ 3 + 2 ^ 3 = 9 = 3 ^ 2 = (1 + 2) ^ 2s3 = 1 ^ 3 + 2 ^ 3 + 3 ^ 3 = 36 = 6 ^ 2 = (1 + 2 + 3) ^ 2s4 = 1 ^ 3 + 2 ^ 3 + 3 ^ 3 + 4 ^ 3 = 100 = 10 ^ 2 = (1 + 2 + 3 + 4) ^ 2s5 = 1 ^ 3 + 2 ^ 3 + 3 + 4 ^ 3 + 5 ^ 3 = 15 ^ 2 = (1 + 2 + 3 + 4 + 5) ^ 2 suppose that when n = k, there is SK = 1 ^ 3 + 2 ^ 3 +... + K ^ 3 = (1 + 2 +... + K ^ 3)
