Math Problem Statement
Douglas’s preferences are represented by the utility function u(x1,x2)=(x1^2)*(x2^3). The prices of x1 and x2 are p1 and p2, respectively. What is the slope of his indifference curve at the point (x1,x2)?

Formulas
u(x1, x2) = x1^2 * x2^3
MU_x1 = 2 * x1 * x2^3
MU_x2 = 3 * x1^2 * x2^2
MRS = - (MU_x1 / MU_x2) = -(2x2 / 3x1)
