Is it true?

[kate]

For every n ∈ N and k odd, is it true that

[tex]2^{n+2}[/tex] divides [tex]a_n = k^{2n} - 1[/tex]?

[eternal]

that true:
k=(1+2q) ,[tex]q\in N[/tex]
after that+binomial theorem discovered by Issac Newton

[leesajohnson]

Yes, its true

Yes, its true...??????

Can you explain please.....

I might as well say it is true as well as everybody else..........

In your first post you didn't ask for a proof, just whether or not it was true! Please tell us what you really want to know in your first post. We can't read your mind!

In the very first response, eternal suggested using the binomial theorem. Do you know what that is?
