To make a compound microscope you can add a 2nd lens to the simple magnifier arrangement. The magnification produced by the objective lens (m) is multiplied by the magnification of the simple magnifier (Me), so the total magnifying power (MP) is increased. That is: MP = m Me.

Calculate how far away from the objective lens you need to place the object to be viewed to produce a magnification of m = - 4.50, if the focal length of the lens is fo = 8.6 cm. Give answer to 3 significant figures.
