Answer

To find the total magnification of the image seen through the microscope, we can use the formula:

extTotalMagnification=extEyepieceMagnificationimesextObjectiveMagnification ext{Total Magnification} = ext{Eyepiece Magnification} imes ext{Objective Magnification}

Substituting in the given values:

extTotalMagnification=10imes20=200 ext{Total Magnification} = 10 imes 20 = 200

Step 2
