Evaluate the integral by changing the order of the integration in an appropriate way.
z goes from 0 to ∞, y goes from x/6 to 3, x goes from 0 to 18
The Attempt at a Solution
to change the integration
z goes from 0 to ∞, y goes from 0 to 3, x goes from 6y to 18
I'm not sure if this is right, so if anyone could steer me in the right direction that would be very nice, thanks in advance.
