is it
7x^3/7 y^4/7 - Lagrange (xp1 + yp2 - m)
then
x = 0 = 3x^-4/7 - lagrange p1
y = 0 = 4X^-3/7 - lagrange p2
lagrange = 0 = xp1 + yp2 - m
my question is -
utuility function U(x y) = 7x^3/7 y^4/7 with prices p1 and p2 for the 2 good x and y and income level M.
using lagrange sove the optimal choice problem and determine the demand function for goods x and y.
Can you start me off
