Answer:
Step-by-step explanation:
The value of az dy is 5a^2ex*y.
Step-by-step explanation:
To evaluate the value of az dy, we need to take the partial derivative of z = 5ex*y with respect to y, denoted as ∂z/∂y, and then multiply it by the value of a.
Given that z = 5ex*y, we can find the partial derivative ∂z/∂y by treating x as a constant and differentiating y with respect to y:
∂z/∂y = 5aex*y
Now, to find az dy, we multiply the partial derivative ∂z/∂y by the value of a:
az dy = a * ∂z/∂y = a * 5aex*y = 5a^2ex*y
