    I cant figure out how to find the differential output voltage of a differential amp. the problem gives me collector resistor and current values. Can you help?

    An opamp doesn't have a differential output. It has a single output. It also doesn't have a collector resistor. It has a very low impedance push-pull output that sinks and sources about 20mA max.

    What are you doing and what do you want to know?

    maybe, posting a circuit diagram would be a good start ;)

    Fully differential op-amps do.
