Simple microscope are used

An object is placed at a distance u from a simple microscope of focal length f. The angular magnification obtained depends

A man with normal near point (25 cm ) reads a book with small print using a magnifying glass : a thin convex lens of focal length 5 cm . a What is the closest and the farthest distance at which he should keep the lens from the page so that can read the book when viewing through the magnifying glass ? b. What is the maximum and the minimum angular magnification (magnifying power ) possible using the above simple microscope ?

Explain the construction of simple microscope and derive its magnification power.

The magnifying power of a converging lens used as a simple microscope is (1+D/f) . A compound microscope is a combination of two such converging lenses. Why don't we have magnifying power (1+D/f_0)(1+D/f_e) . In other words, why can the objective not be treated as a simple microscope but the eyepiece can?
