Answer: For 10X objective =80X
For 40X objectives =320 X
Explanation: The magnification of a light microscope can be computed by multiplying the power of the eyepiece by the power of the objective lens.
For the 10X objective = power of eyepiece × power of objective lens= 8X × 10X
= 80X
For the 40X objective = power of eyepiece × power of objective lens= 8X × 40X
= 320X
