Answer:
10mm , 0.0625mm
Step-by-step explanation:
The size of the image of a cell that is 0.05mm in diameter viewed under a microscope with a 200x power lens would be 0.05mm * 200 = 10mm.
The size of the actual cell if an image of a cell is 50mm in diameter when viewed under a 800x microscope would be 50mm / 800 = 0.0625mm.
