Answer:
Magnification of an optical microscope is the ability of a microscope to magnify the image of the sample when placed in a microscope.
The magnification is the result of the multiplication of the power of the lenses of an objective lens near the object and the ocular lens near the eye.
It can be represented as :
magnification = objective lens x ocular lens
Since in the given question,
power of objective lens = 10x and the power of the ocular lens = 5x
therefore magnification will be 10 X 5= 50x
Thus, the magnification will be 50x
