# Thread: Differentiation

1. ## Differentiation

Could someone help with this problem, let me know if I am correct. Thanks

Y = [(AL)1/2 +BK1/2]2
dY/dK = [1 +BK1/2]2

2. Y = [(AL)1/2 +BK1/2]2

Assuming A,L and B are comstants

Think of this as Y = u^2 where u = [(AL)^(1/2) + BK^(1/2)]

dy/dk = 2u du/dk = 2[(AL)^(1/2) + BK^(1/2)] *(1/2BK^(-1/2))
