By the principle of mathematical induction, prove that, for `nge1`
`1^(3) + 2^(3) + 3^(3) + . . .+ n^(3)=((n(n+1))/(2))^(2)`

Answer

` = ((K + 1)^(2)(K + 2)^(2))/(4) = [((K+1)(K +2))/(2)] = RHS `
because p(K +1) ` is true
` because ` By the principle of mathematical induction,p(n) is true for all value of n.
