34. Incorrect. The answer is false, not true. Treat L^{1/4}E^{1/3}
as if they were constant, which gives you the partial derivative as ¶Q/¶K =
1/2K^{-1/2}L^{1/4}E^{1/3}. Note if you want to know whether marginal product is increasing
or decreasing take the second partial, which equals –1/2*1/2*K^{-3/2}L^{1/4}E^{1/3}. Since this value is negative we have
diminishing marginal product.
