I looked up that the summation formula for x^3 is the square of the summation formula for x. In other words (1 + 2 + 3 +…)^2 = 1^3 + 2^3 + 3^3 + … and I want to know if that means the summation formula for x^6 would be the square of the summation formula for x^2 because (x^3)^2 = x^6 and x^2 = x^2.
