Q: Which formula correctly represents the calculation of total magnification in a compound microscope?

$Total\ Magnification = Ocular\ Lens\ Magnification \times Objective\ Lens\ Magnification$

Q: Which formula would you use to calculate the field of view diameter at high power if you know the field of view at low power and the magnifications?

$Field\ of\ View_{high} = \frac{Field\ of\ View_{low} \times Magnification_{low}}{Magnification_{high}}$
