    Working with powers

    I am trying to figure out this progression from a book I am reading and not having a lot of luck.

    A is proportional to B^2.8

    A is proportional to B x C^2

    Therefore A is proportional to C^3.1

    Re: Working with powers

    You have to be more clear with your notation:
    A is proportional to B^{2,8}
    A is proportional to B\cdot C^2
    Therefore A is proportional to C^{3,1}
    Is this the exercice?
