find in (1+x+x^2)(1+x)^n the coefficient of (a) x^7 (b)x^8; and © x^r for 0<=r<=n+2 i've no idea wher to start this one

give us some interesting/strange/wierd facts about uranium

i'm going in to cs major for undergrad. good thing?

C++ or JAVA, I've seen science institutes use java.

im confused, who can explain this in english?

for me i just observe, no indicator really, I believe that excess does no harm to the product? if you have any ways to indicate, either a ratio or any other method, it would be greatly appreciated since AgNO3 isnt the cheapest thing in the world.

thanks a lot for this info man. I believe there is another way involving using this reaction: AgNO3+KCl=AgCl+KNO3 so the basic idea is to get the solid part AgCl out and use stoichiometry to figure out percent composition which one do you think is easier to do? btw, what is this method i just stated called? thanks a lot

how do you separate & calculate the percent composition of potassium chloride and sucrose?
