Final answer:
The total magnification of the object viewed through the microscope is 2000x.
Step-by-step explanation:
The total magnification of an object viewed through a light microscope with oculars that magnify 20x and a high-power objective lens that magnifies 100x is 2000x. To calculate the total magnification, you multiply the magnification of the objective lens by the magnification of the ocular lens. In this case, 20x multiplied by 100x equals 2000x.
