Are there any physical laws that are exact? How can we know if one is?

To clarify, I mean without taking into account universal constants that we only know approximately, and given the perfect situation in which the laws are (supposed to be) valid.

For example, we know Newton's 2nd law is only an approximation valid for low velocities, but if we consider relativity, can't the v^2/c^2 term in the gamma factor not possibly be v^2.0001/c^0.0001?

That's not the point of physics.

But from (unprovable) symmetry: conservation of linear momentum, conservation of angular momentum, and conservation of energy are absolute.
