Hi everyone!

This is an economics problem, but even if you know nothing about economics, you might be able to help...

I am given the slope of the PPF to be

[z(K^0.5)(N^-0.5)]/2, so I know the the negative (-) of the slope of the PPF is the marginal productivity of labour (MPn).

I also know that z = 1/2 and K = 4

What I think I need to do to determine the equation for the PPF is to take the antiderivative of the slope. So I subsituted in z and K to get:

-[(2^0.5)(N^-0.5)]/2

but here comes the part where I forget my calculus skills. I got

(2^0.5)(N^0.5) as my final answer but I'm not sure this is right.

Is the antiderivative of -0.707(N^-0.5) just equal to (2^0.5)(N^0.5)?

Thanks for your help!

Sorry about the lack of Math brackets, I tried putting them in initially but it reallllly messed up my equations, so apparently i don't know how to use them!
