calculate integral
Hello
I wounder if someone can calculate y? in the figure below from the function y=(x/((11.08^0.3127340824*2899653^0.2153558052*e^20.700 37453)/0.8515))^(1/-0.9232209738)
The yellow area is 4673535732. And then how do I setup the integral function?

Well, most of that mess is just a constant so your function is of the form
$f(x) = ax^b$

So to find the area you would be finding the area between the function and the y axis:
$A = \int_y^{2704}f^{-1}(y)~dy$

Give that a shot. If you need more help, let us know.

Sorry dan,iam uploaded the wrong figure(Doh) My problem is to calculate y? and I don´t know either the height or the breadth of the yellow rectangle.I just know that the area is 4673535732 and the functiony=(x/((11.08^0.3127340824*2899653^0.2153558052*e^20.700 37453)/0.8515))^(1/-0.9232209738)
