I can't seem to find information on this specific question i have.

So i'm taking the partial derivative of this equation for both x and y

I know how to do it for y, but I am not seeing something with respect to x

fx(x,y)= x^7 + 2^y + x^y

2. Relevant equations

3. The attempt at a solution

So this is what I thought it should be

7x^6 + 1 + yx^(y-1)

I guess the answer is 7x^6+yx^(y-1) according to cramster and there is no 1 in it.

Why does 2^y not go to 1?

I would think because you treat y as a constant that it would go to zero and 2^0 is 1

What is wrong with my reasoning?

Thanks for reading
