Quick Partial Derivatives question - exp(x+z)

[maks4]

Homework Statement

Finding the partial derivative with respect to y, so del(f)/del(y)

Homework Equations

exp(x+z) - that is e^(x+z)

The Attempt at a Solution

I firstly thought this was just e^(x+z) but then i realized, shouldn't it be just 0? Since you're finding the partial derivative with respect to y, and since there's no y variable in there, wouldn't it be 0, ie treating the whole equation as a constant?

Yes it would.
