We are told that ∑k=0nkm \displaystyle \sum_{k=0}^n k^m k=0∑nkm is a polynomial in nnn of degree m+1m+1m+1.
For constants a,ba,ba,b, we have∑k=1nk2015=a⋅n2016+b⋅n2015+… \displaystyle \sum_{k=1}^n k^{2015} = a \cdot n^{2016} + b\cdot n^{2015} + \ldots k=1∑nk2015=a⋅n2016+b⋅n2015+….
Find ba\frac{b}{a}ab.
