Solution

 the power of the lens

For a simple microscope in normal adjustment, the object is placed at a distance equal to  f (the ​focal length) from the lens, And the angular magnification is given by the relation

m = D/F.

For u < f , m =D/f +1.
Power of the lens = 1/f 
Angular magnification depends on power.
