Thread: 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

You have to be more clear with your notation:
is proportional to
is proportional to
Therefore is proportional to
Is this the exercice?

My apologies, yes that is the exercise.

I think this is gives the solution

Aha, Thank you PASCALfan, now I can see where I was going wrong, again thank you very much.
