In the proof the do not prove that statement they just say because of that we can conclude bla bla should you prove that part in order to make a proper proof?
So well the thing is that you have this number n=p!+1
As p is the biggest prime number n should be divisble with some number. We do not know any number which is divisble with p! and 1 but 1. And we have to find a number larger than that - but we cannot. As that the definition of a prime...
ZioX I must say that I do not really get it because I cannot really see what it has to do with the prime numbers less than p, and how they should be divisble with n.
I have to prove that there excist an infinite number of prime numbers
In that proof I apply that:
n=p!+1 (where p is a prime number)
this number (n) is not divisible with any prime number less than or equal to p. Why is that? Is there anyone who could please explain this to me or maybe...
In science proving something by making it linear is a cmmon approach.
For instance you can write some laws on this form.
y=a*log(x)+b
But there lies my problem, because I cannot see how this should represent a linear line. So please does this represent a line? ANd if yes how come?
Well the main problem is that I know I have to solutions.
Ag(s)+Ag+(aq)+NO3-(aq) ->
I have no idea what that will become the same about the zinc where it is.
Zn(s)+Zn2+(aq)+2NO3-(aq) ->
That is kind of where I am stuck...
Homework Statement
I have got a battery with two half cells.
One cell with.
A silver rod in a 100 mL AgNO3 0,025 M solution.
One cell with.
A zinc rod in a 100 mL Zn(NO3)2 0,150 M solution.
So my question is what reactions happen?
And which reaction is the electricity providing...
