Answer:
Multiply the magnification of the lenses together. For example, if the eyepiece magnification is 10x and the objective lens in use has a magnification of 4x, the total magnification is 10 × 4 = 40. The total magnification of 40 means that the object appears forty times larger than the actual object.
