Answer:
Step-by-step explanation:
The question is incomplete. Here is the complete question.
Find the partial derivatives indicated Assume the variables are restricted to a domain on which the function is defined. z=
+
+
a) Zx b) Zy
In differentiation, if y = axⁿ, y' =
. Applying this in question;
Given the function z = x⁸+
+

Note that y is treated as a constant since we are to differentiate only with respect to x.
For Zy;

Here x is treated as a constant and differential of a constant is zero.
