Example
In the cookie factory, the production function is `q (K, L) = K L^2`.
Tomorrow, they have to make 100 cookies. The combinations of Capital (K) and Labor (L) required to make 100 cookies satisfies
$$ \begin{align*} q (K, L) &= 100 \\ K L^2 &= 100 \\ K &= \frac{100}{L^2} \end{align*} $$Question
The production function is now `q(K, L) = K^2L^3`.
What is the equation of the isoquant representing the production of 100 cookies? Draw that isoquant.
The isoquant satisfies `q(K, L) = K^2L^3 = 100`.
Solving for `K`.
$$ \begin{align*} Y^2&= \frac{100}{L^3}\\K &= \frac{100^{\frac{1}{2}}}{L^{\frac{3}{2}}}\\K &= \frac{10}{L^{\frac{3}{2}}}\end{align*} $$
