EXAMPLE: \frac{dc}{dv} = \frac{160}{v} + \frac{v^2}{100}


                   \frac{dc}{dv} = -160 v^{-2} + \frac{2v}{100}


                   -160 v^{-2} + \frac{2v}{100} = 0

                                

Step 3: Solve the equation to find the unknown value.


            EXAMPLE:   -160 v^{-2} + \frac{2v}{100} = 0


                                     \frac{-160 * 100}{v^2} + 2v = 0


                             -160 * 100 + 2v^3 = 0


                                                       2v^3 = 16000


                                                         v^3 = 8000


                                                         v = 20
