im not understanding this. could you please help me and show your work!

2. Take the partial derivative of y = (2 + x2) (2:4) with respect to x (Hint: Product rule} 3. Take the partial derivative of y = (1:332 with respect tax {Hint: Quotient Rule] 4. If: = ftp) = 2 + 3:2 and y = f(x) = ln(4-x) take the partial derivative of z with respect tax {Hint: Chain Rule]
