I have a full solution to it - I'm going to bed so you want me to post it as long as you don't look?

I attempted it several times but gave in and had a look at your solutions - WOW! That was a very tricky one indeed, well done :smile:

Thank you as well, appreciated!

Yeah potentially. In my papers, I put strictly on-spec material, but for my worksheets, well, we can have some fun, can't we :tongue:

You could put some symbol by the question to mean "extension material, not on specification" so that you don't scare people into thinking they are supposed to be familiar with the material.

That way your worksheets cater for both the ordinary students and for the more adventurous ones.

It's incorrect, it should be left as

15(2^{4k})

Or

15(4^{2k})

Wait, this is actually interesting, there are an infinite number of ways to express that number, and I think (uncountably?) many.
