$$int_Bfracx^3y^3dlambda_2,$$ where $$B=(x,y): x^2<8y<8x^2; y^2<x<8y^2$$ This is the first time for me, where $2$ variables depend on each other in this manner. I wanted to do some smart substitution, but can't figure out one. Any help appreciated. I also drew this area, but it does not much easier, since it is a bit irregular shape. What is the method in this type of situations?
