1. ## Economic based problem.

Hi guys,

I'm stuck with a simple calculus problem.

I have to maximise wrt to both x 1 and 2 and express x1 in terms of x2.

p.x11/2x23/4 - (5x1 + 10x2)

I know this should be quite but I have forgotten all the laws etc I need to use. Apparently the answer should be:

x11/2 = 40/p.x23/4

Thanks for any help

Differentiate with respect to $x_1$ and $x_2$ and set them equal to 0. That will give two equations to solve for $x_1$ and $x_2$.
