how do i solve the following?
When you have experience with proving statements like this, you know what the poster means even if (s)he doesn't say it.
Was this a question that a teacher/professor gave you? It should be worded 9^p and 25^p for p ≥ 1, aka, natural numbers.
I am always very confused, but thanks for the sympathy.
Oh, and I meant to say integer larger or equal to 0 in my post, since this was about integers and nothing else. Sorry if that confused you, irspow.
Thanks Ricky, I got it now :]
Let n = 1:
I think Enfy said any number greater than or equal to zero. I dont think that there is anything to prove otherwise. If p is an integer, then p + 1 would also be an integer the equation would only produce a series like;
I was skeptical at first, but it seems that induction is the way to go on this one.
Inductive assumption, 216, and 600 are all divisible by 4.
I've tried the induction proof, but I didn't get too far with it (I'm still not too comfortable with it btw). I might try something similar to what Ricky posted before he edited his post, though I was confused with one of the steps he provided.
p is any number? Only integers, right?
Edit: Ah, spotted a large error in my proof, fixing it right now.
I hope you get your answer here. I was looking for a similar definition in an earlier thread, but a clear one never emerged.
I've been trying to solve this for a while, but without any good result. I could definitely need some help :]
