(Variable Change) - How to apply Gauss Theorem or Stokes to get volumes?

69 Views Asked by At

Calculate $$I = \iiint_V \frac{1}{(xyz)^2}\cdot\frac{1}{1+x^{-6}+y^{-8}+z^{-10}}\,dx\,dy\,dz$$

We know $\Omega$ is tuple $(x,y,z) \in \mathbb{R}^3$ and $x>0$ , $y>0$ , $z>0$

I don't now how to use Stokes Theorem or Gauss-Divergence Theorem. I think that i need a surface for get integration limits or $\vec{n}$.

Thank you so much

Edit:

$\Omega$ is a function limited on the entire first octant.

$\Omega$ is the function and $V$ is "Volume" closed on this function.

I understand "Calculate this Volume". I get this exercise in a Multivariable calculus test. I really don't know how to propose this problem. I think i need more information for calculate I. Maybe my teacher have been wrong?

The exactly problem was: I translated this from Spanish to English.

Calcula $$I = \iiint_V \frac{1}{(xyz)^2}\cdot\frac{1}{1+x^{-6}+y^{-8}+z^{-10}}\,dx\,dy\,dz$$ siendo $\Omega$ las ternas de números reales $(x,y,z)$ tales que $x>0$, $y>0$, $z>0$.

Edit 2:

I asked my teacher how to resolve this. He answered me that I have to make an easly variable change. Sorry for my mistake, we don't need Divergence Theorem. I will try with the following change but I think that I won't resolve this integrate.

\begin{array} & x = a \rho \sin^p{\varphi} \cos^q{\alpha} \\ y = b \rho \sin^p{\varphi} \sin^q{\alpha} \\ z = c \rho \cos^p{\varphi} \end{array}
