Find the first partial derivative with respect to l
∂g∂w=l1
Simplify
w=lg
Find the first partial derivative by treating the variable l as a constant and differentiating with respect to g
∂g∂w=∂g∂(lg)
Use differentiation rule ∂x∂(g(x)f(x))=(g(x))2∂x∂(f(x))×g(x)−f(x)×∂x∂(g(x))
∂g∂w=l2∂g∂(g)l−g×∂g∂(l)
Use ∂x∂xn=nxn−1 to find derivative
∂g∂w=l21×l−g×∂g∂(l)
Use ∂x∂(c)=0 to find derivative
∂g∂w=l21×l−g×0
Any expression multiplied by 1 remains the same
∂g∂w=l2l−g×0
Any expression multiplied by 0 equals 0
∂g∂w=l2l−0
Removing 0 doesn't change the value,so remove it from the expression
∂g∂w=l2l
