Is Curl F Non-Zero in a Conservative Field?

It seems there are some problems on the test.
I find that Curl F is not zero, that means the field is not exact.
Am I right?

I agree with you that Curl F ≠ \vec 0 so F is not the gradient of a scalar function, which I presume is what you mean by "not exact".
