I took calc a year ago and did ok, but now i need to know some calc for an econ class im in.

Here's a sample question...

Q=10L^.75 K^.25

In my calc class we just had to do the math, and i would multiply the exponent to the coefficient and minus the exponent by 1. I'm 99.9% this is correct.

But my econ teacher wants us to caclucate to sets:

a. calculate derivative Q/derivative L

b. calculate derivative Q/derivative K

I'm lost on that part. Thanks
