Question

Find the derivative of: (L+m)(V+n)=k

Answer 1

derivative with respect to what?

Answer 2

dV/dL

Answer 3

m, n, k are constants?

Answer 4

yes

Answer 5

\[\large (L+m)(V+n)=k \]
\[\large \frac{d}{dL}[L+m]\cdot (V+n)+(L+m)\cdot \frac{d}{dL}[V+n]=0 \]
\[\large 1\cdot (V+n)+(L+m)\cdot \frac{dV}{dL}=0 \]
can you take it from here to solve for dV/dL ?

Answer 6

maybe a better way would've been to just multiply out the binomials firs....
it don't matter, the answer should be the same...
