The Cobb-Douglas function Q = A·Kᵅ·L¹⁻ᵅ describes how capital and labor combine to make output. Isoquants show input mixes yielding the same output; the budget line shows what you can afford. Production is maximized where the budget line just touches the highest isoquant — the cost-minimizing input mix, splitting spending by the exponents.

Optimal capital K12.5

Optimal labor L16.7

Output Q14.4

Governing equation

Q = A K^{0.50} L^{0.50} = 14.4, K^{*} = \frac{α B}{r} = 12.5, L^{*} = \frac{( 1 - α ) B}{w} = 16.7

Reading this result: Cost-minimizing plan spends 50% of the budget on capital and 50% on labor — the exponents fix these shares no matter what r and w are; prices only change how many units of each that money buys.
