Question

For alln∈N≥1(son≥1), and usingweakinduction, prove that:n∑i=1i3=[n(n+ 1)2]2Note that this result means that the sum of the third powers of the first strictly positive integers is equal to the sum of the same integers, squared=

Answer 1

Explanation:

hello,

the question is not really clear. i believe the intended equation would be

`\sum_(k=1)^(k=n) k^3=((n(n+1)))/(4)`

please check the attached file for the step by step proof.
