MRTS=-400
Explanation:
This equation basically says that the output that this firm produces is a function of Labor and Capital, where each isoquant represents a fixed output produced with different combinations of inputs
The equation for the isoquant when Q = 2,000 can be found as follows
Q=(K^{0.5})*(L^{0.5})
where Q = 2000
2000=(K^{0.5})*(L^{0.5})
(K^{0.5})=
K=
MRTS=
where
K=
K=
K=
K=200^{2}
K=40000
MRTS=-400
