Answer:

1.compare the image of the letter that you see using unaided eye with what you see through the microscope

The eye of the microscope is too transparent and too  fussy to our naked eye which sees only big things.  That microscopes eye is  too close to our ears.  

You can see the true distance of the number by using your own eyes  By using a telescope the distance of the letter is greater than the real distance.

The Compound Microscope

A lens or a glass (a glass piece that is  To magnify an image, make it appear bigger).  But how far is a easy thing?  Loupe can make things bigger: about 8-10 folds, that is.  To increase this magnification, the lenses  must be added, one behind another (compounded).  This way we are able to magnify  the image up to 2000 times its size.  In two steps, the classic compound microscope magnifies: first, with an objective  lens that produces an enlarged image of the object in a 'real' plane.  The ocular lens or eyepiece then magnifies  this actual image to create the virtual image.

2.Going to high power on a microscope decreases the area of the field of view. The field of view is inversely proportional to the magnification of the objective lens. ... The specimen appears larger with a higher magnification because a smaller area of the object is spread out to cover the field of view of your eye.

3.you can see the whole letter e using the scanner and the low power objective, because these two allows you to see the whole details of your specimen

4.The advantage of using an objective with higher magnification is an increase in detail can be viewed. The disadvantage of viewing at a higher magnification is that less of the slide can be viewed

5.To figure the total magnification of an image that you are viewing through the microscope is really quite simple. To get the total magnification take the power of the objective (4X, 10X, 40x) and multiply by the power of the eyepiece, usually 10X.

Hope it helps :)
