please, help me !!
here, I found that,
f(1)* f(2)* f(3) *…f(n)=n, because the others will ultimately be cancelled out by each other.I am almost sure about this.
then, r=1 or r=0; but I am not so sure about this.
I can’t continue it, I am not understanding how will I find out the value of s.
So please help me, and correct me if I am wrong
You got it wrong.
f(1)*f(2)*f(3)*f(4)*f(5)*f(6)…=f(1) * 2/f(1) * f(3) * 4/f(3) * f(5) * 6/f(5)…=2 * 4 * 6…
Means it is not equal to n. It is 2 * 4 * 6…
I think if you try, you can solve this to find out the value of r and s.
