What is the difference between the two? The topic we are currently reading about is Set Cardinality. There are a couple of definitions listed in the book that seem to define them as different properties of sets. Is there a difference between the two or are they different terms with the same...

I think you are right about reviewing exponential properties. Thank you so much. Last question... What happened to the +1 where you wrote 22n+1−22n ? Thanks again, my friend. I now know exactly where I'm lacking and what I need to review.

Thank you! That definitely gives me an idea and I will now brush up on my laws of exponents. Haven't used it in a while. Looking at the answers in the back of the book, #c is not a solution for {an} since it is not equal to 2n. It also mentions that #d is a solution since 4n satisfies the...

Hello - I am having a tough time understanding the problems in the attached picture (Problem 13). My issue is understanding how I plug in the proposed solutions, specifically those that include n. I am able to solve A and B but unable to solve the rest. For instance, how do I plug in C or...
