I'll use subscript notation for brevity, i.e.
.
By the chain rule,



We have

and

When
, we have

and the partial derivatives take on values of

So we end up with

The product of two radicals is equal to the radicand. The square root deletes itself.
So the result is y^3
Answer:
C
Step-by-step explanation:
The answer to this problem is 16.
To solve we must follow the order of operations.
8/2 is 4.
2+2 is 4.
So, now we multiply 4(4) and will get 16 as the answer
So, 16 is the answer.
