Question

Given the production function $Q = 2 \cdot K^{1/3} \cdot L^{2/3}$, find the output level when 8 units of capital and 27 units of labour are used.

The correct answer is
36

Production Function Calculation

The problem asks us to calculate the output level ($Q$) using a given production function and specific amounts of capital ($K$) and labour ($L$).

The production function is given by:

$ Q = 2 \cdot K^{1/3} \cdot L^{2/3} $

We are provided with the following input values:

  • Capital ($K$): 8 units
  • Labour ($L$): 27 units

Calculating Output Level

Substitute the given values of $K$ and $L$ into the production function:

$ Q = 2 \cdot (8)^{1/3} \cdot (27)^{2/3} $

Now, let's calculate the terms involving exponents:

  • The cube root of 8, which is $8^{1/3}$, equals 2.
  • To calculate $(27)^{2/3}$, we first find the cube root of 27 ($27^{1/3}$), which is 3. Then, we square this result: $3^2 = 9$.

Substitute these calculated values back into the equation for $Q$:

$ Q = 2 \cdot 2 \cdot 9 $

Performing the final multiplication:

$ Q = 4 \cdot 9 $

$ Q = 36 $

Therefore, the output level is 36 units when 8 units of capital and 27 units of labour are used.
