No the focal length on both FX and FX are the focal length of the lens.
The apparent difference is due to the difference in sensor size. 
A FX has more area to capture the image than a DX and the DX provides a crop of the FX image of 1.5x which gives and apparent focal length equivalent increase of x1.5
