how to integrate this equation?(adsbygoogle = window.adsbygoogle || []).push({});

∫∫e^-x^2 e^-x'^2 / |x-x'| dx^3 dx'^3 lower limit is 0 and upper limit is inf for x and x'

the result is an error function. But I would like to know the details of the process of integration.

some one suggest me to change the variable to x+x'=u x-x'=v but I got stucked. Can some one gave me any further suggestions or hints. Much appreciated!

With Best Regards
