WebExample 1: Find the sum of cubes of the first 10 natural numbers. Solution: By applying the sum of cubes of n natural numbers formula, we have S n = [n 2 (n + 1) 2 ]/4, where S is the required sum. In the given question, the value of n is 10. So, by substituting the value of n, we get, S 10 = 10 2 × (10+1) 2 /4. WebSince every integer is congruent to its own cube modulo 6, it follows that every rational integer is the sum of five cubes of integers. In 1966, V. A. Demjanenko proved that any …
