2n2 / n = 2n

It is: 2n^2 -5n -42 equals (2n+7)(n-6) when factored

4n - 2n = 84 2n = 84 n = 42

I will assume that we are taking d/dx, not d/dn. There are two ways to interpret what you asked. First way is (sinx)^(2n). Second way is sin(x^(2n)). First answer: 2n(sinx)^(2n-1)(cosx)=2ncosx(sinx)^(2n-1). Second answer: cos(x^(2n))(2nx^(2n-1)).

It is the exponential series of 2, or 2n but offset by one value.

4n - 2n = 18 Therefore, 2n = 18 Therefore, n = 18/2 = 9

n(2n - 1)(2n + 7)

For example: * 232Th-------n,gamma-------233Th---beta minus---233Pa--beta minus--233U---n,2n-----232U * 232Th-------n,gamma-------233Th---beta minus---233Pa-----n,2n-----232U
