 Mar 20 asked Is there efficient way of finding last number in following sequence Mar 19 revised For which minimal $k$ true is that ${4}^{k}\cdot n\leq \displaystyle\sum^{n}_{i=1}{a}_{i}^{k}\leq {5}^{k}\cdot n$, ${a}_{i}\in {1,2,3,4,5,6}$? edited tags Mar 19 revised For which minimal $k$ true is that ${4}^{k}\cdot n\leq \displaystyle\sum^{n}_{i=1}{a}_{i}^{k}\leq {5}^{k}\cdot n$, ${a}_{i}\in {1,2,3,4,5,6}$? edited tags Mar 19 revised For which minimal $k$ true is that ${4}^{k}\cdot n\leq \displaystyle\sum^{n}_{i=1}{a}_{i}^{k}\leq {5}^{k}\cdot n$, ${a}_{i}\in {1,2,3,4,5,6}$? deleted 1 characters in body; edited tags Mar 19 revised For which minimal $k$ true is that ${4}^{k}\cdot n\leq \displaystyle\sum^{n}_{i=1}{a}_{i}^{k}\leq {5}^{k}\cdot n$, ${a}_{i}\in {1,2,3,4,5,6}$? edited title Mar 19 reviewed Approve For which minimal $k$ true is that ${4}^{k}\cdot n\leq \displaystyle\sum^{n}_{i=1}{a}_{i}^{k}\leq {5}^{k}\cdot n$, ${a}_{i}\in {1,2,3,4,5,6}$?

Mar 19 comment What is sum of occurrences of zeros, at the end of integers, up to number $n$? @Erick Wong good point Mar 19 accepted What is sum of occurrences of zeros, at the end of integers, up to number $n$? Mar 19 comment What is sum of occurrences of zeros, at the end of integers, up to number $n$? @JB King good point, sometimes strange things happen aroud the zero :) Mar 19 comment What is sum of occurrences of zeros, at the end of integers, up to number $n$? yes, but what about closed form solution ? it seems to have something to do with n(n+1) sum ?

Mar 11 comment Checking Sudoku - sufficient sums yes integers hjk,hj Mar 11 comment Checking Sudoku - sufficient sums ok I have not answer but information that make my question invalide math.stackexchange.com/questions/157682/… my condition could be substituted by taking sums of 2^value, but I'm not sure on 100% Mar 11 asked Checking Sudoku - sufficient sums Mar 6 comment Are there any Heron-like formulas for convex polygons?
