    No idea how to word this. Finding the gradient with vector?

    Hmm I think I may have to post the question in full. My original post is just a small part of a bigger question (about Gauge transformations) so I am probably going about it wrong.

    Sorry it is a vector. I was trying to mimic exactly how it is written in front of me.

    Stuck on an equation involving powers - I only have 1 unknown

    Thanks but I have probably just messed up somewhere, as I don't think it will be that much hassle. https://www.physicsforums.com/showthread.php?p=4716123#post4716123

    It represents the rolls of a dice. I'm going to post the full question over in the physics homework subforum.

    Stuck on an equation involving powers - I only have 1 unknown

    Hi all sorry the title couldn't be more descriptive. I'm having a bit of a brain block with this equation (it's the very end of a problem). N(\frac{5}{6})^{N-1} > \frac{27}{5} My line of thought was to get the first N in terms of the power N-1.. How do I find N?
