Math Problem Statement

L= 0.8logX+0.2logY+λ(5000-4x-2Y)

Solution

You have the equation:

L=0.8log(X)+0.2log(Y)+λ(50004X2Y)L = 0.8 \log(X) + 0.2 \log(Y) + \lambda(5000 - 4X - 2Y)

It looks like this might be a Lagrange multiplier problem where LL is the Lagrangian, and you might be trying to find the maximum or minimum of a function subject to a constraint. The term λ(50004X2Y)\lambda(5000 - 4X - 2Y) suggests a constraint of the form 50004X2Y=05000 - 4X - 2Y = 0.

Steps for solving the problem (if optimization is the goal):

  1. Set up the partial derivatives of LL with respect to XX, YY, and λ\lambda, and set them equal to zero to find critical points.

    • LX\frac{\partial L}{\partial X}
    • LY\frac{\partial L}{\partial Y}
    • Lλ\frac{\partial L}{\partial \lambda}
  2. Solve the system of equations that arises from these partial derivatives.

Would you like me to walk you through the detailed process of solving this system, or clarify the context of your equation (such as whether you are optimizing a function)?

Tip:

Logarithmic terms in optimization problems often suggest that the variables XX and YY should remain positive for the logarithm to be defined.
