**Math**

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?

**math**

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???

thank you for your help!!

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?

**Chem 2068 lab**

Once I have the molarity for KHP which is 0.0027 M, and i add 14.48 mL of NaOH to the solution, what is the concentration of NaOH in the solution.
