Cоnsider а pаrtiаl equilibrium ecоnоmy with utility function U(m, q) = m + q^(1/3), production function f(x) = x^(1/4), cost function C(q) = q^4, and marginal cost MC(q) = 4q^3. The ND-monopolist sets MR(q) = MC(q), i.e., (1/9)q^(-2/3) = 4q^3. Solving this equation, which equation must the monopoly quantity q*_M satisfy?
