1. The problem statement, all variables and given/known data

x<1

2. Relevant equations

∬_(z<1)▒z*dx*dy/〖(1-z^**x)〗^2

3. The attempt at a solution

It is not at all urgent that I solve this problem though it well may be that it is urgent for you to solve it! In any case, that template is designed as it is to make sure that you do what is required for help- show your attempt at the problem.

If you were to do that it might also help us understand what the problem is. You have a symbol that shows up only as a blob on my reader. Also you have two integral signs with lower bound "z< 1" which makes no sense. You have the peculiar notation "^**" which means nothing to me. Finally, your double integral is with respect to x and y but you have "z" in the integrand. What is z in terms of x and y?

Isolet,
Your image was way too large, at 2592 x 1936, and required viewers to scroll sideways and vertically to see the entire image. Images should be no larger than about 800 x 600 pixels.

Please scan your image again and repost a smaller image.

Well, you still haven't made it clear. As I said in my first response, your integral is with respect to x and y but you have z in your integrand. What is the relation between z and x,y? Are you working in the complex plane with z= x+ iy?

it is clear enough and that is the question . it is the question which is asked in the doctorate programme.
