help me!!! (partial derivative)

1. Take the derivatives of the following functions with respect to x (∂/∂x):

2. Calculate the partial derivative with respect to x (∂/∂x) and y (∂/∂y ):

3. Let g = f (x, y) = ax2 + bxy + cy2 . Calculate the partial derivative with respect to x

(∂g/∂x) and y (∂g/∂y).

4. Let g = f (x, y, z) = xa yb zc . Calculate the partial derivative with respect to x (∂g/∂x),

y (∂g/∂y) and z (∂g/∂y).

5. Let g = f (x, y) = a ln x + bln y . Calculate the partial derivative with respect to x

(∂g/∂x) and y (∂g/∂y).

6. Let g = f (x, y) = eax+by . Calculate the partial derivative with respect to x (∂g/∂x) and y

(∂g/∂y).

i do not exactly understand how to solve partial derivative (Worried)

please help me thanks!
