Is i^2=-1 for how many integers N is (N+i)^4 an integer? so far i have factored out (N+i)^4 to be ... n^4+2n^2+1 i would suggest checking that, but from there i don't know where to go...doesn't it work for every integer?

can someone explain that??? because if you do 1/2 of 17, 1/3 of 17, and 1/9 of 17 than compare it to what they actually got...they ALL got more than their fair share... is that the answer than? how is it just the oldest???

Did i get it wrong? It has KHP molar mass at 204.33 g/mol and we use 0.556 g of KHP dissolved in water. THen if 14.48 mL of NaOH is used to reach endpoint, it needs the concentration of NaOH?
