Function
Find the first partial derivative with respect to c
Find the first partial derivative with respect to d
∂c∂k=102d
Evaluate
k=cd×102
Use the commutative property to reorder the terms
k=102cd
Find the first partial derivative by treating the variable d as a constant and differentiating with respect to c
∂c∂k=∂c∂(102cd)
Use differentiation rule ∂x∂(cf(x))=c×∂x∂(f(x))
∂c∂k=102d×∂c∂(c)
Use ∂x∂xn=nxn−1 to find derivative
∂c∂k=102d×1
Solution
∂c∂k=102d
Show Solution

Solve the equation
Solve for c
Solve for d
Solve for k
c=100dk
Evaluate
k=cd×102
Use the commutative property to reorder the terms
k=102cd
Rewrite the expression
k=102dc
Swap the sides of the equation
102dc=k
Divide both sides
102d102dc=102dk
Divide the numbers
c=102dk
Solution
c=100dk
