"WebStep (1) To apply the divergence test, we replace our sigma with a limit. To apply our limit, a little algebraic manipulation will help: we may divide both numerator and denominator by the highest power of k that we have. Taking the radical into account, the highest power of k is 1, so we divide both numerator and denominator by k1 = k . " - Sympy divergence
