Earth is being added to a pile so that, when the height of the pile is h metres, its volume is V cubic metres, where V = (h6 + 16) 1 2 − 4.Find the value of dV/dh when h = 2.

As V=(h 6 +16) 1/2 -4 , the chain rule can be used to calculate dV/dh. dV/dh=3h 5 (h 6 +16) -1/2 h=2 can be substituted in to find the solution. 3 2 5 (2 6 +16) -1/2 =10.73
