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.x_{1}^{1/2}x_{2}^{3/4}- (5x_{1}+ 10x_{2) }I know this should be quite but I have forgotten all the laws etc I need to use. Apparently the answer should be:

x_{1}^{1/2}= 40/p.x_{2}^{3/4 }

Thanks for any help
