To find the minimum value of x²yz³ subject to the constraint 2x + y + 3z =1, we can use the method of Lagrange Multipliers.
The method of Lagrange Multipliers is used to optimize a function subject to a constraint.
The Lagrangian function is defined as: L(x,y,z,λ) =
where λ is a Lagrange multiplier.
The goal is to find the critical points of the function, which are the points where the partial derivative of L with respect to x, y, z, and λ are equal to zero.
∂L/∂x = 2xyz³ + λ(2) = 0
∂L/∂y = x²z³ + λ(1) = 0
∂L/∂z = x²yz² + λ(3) = 0
∂L/∂λ = 2x + y + 3z - 1 = 0
Solving this system of equations gives us:
x = 0, y = 0, z = 0 and λ = 0.
