【Abstract】 Four power sum formulas of natural numbers expressed by Stirling numbers of second kind are discussed.By means of the definition of rising factorial and falling factorial,the recursive relation of the power sum of each order is obtained,and the formula of the power sum expressed by the Stirling numbers of second kind is given by means of solving the infinite matrix equation,and the equivalence between them is proved.更多还原
