A compound microscope has two lenses. One lens has a magnification of 15 and the other lens has a magnification of 40. What is the total magnification of the microscope?

A. 55
B. 150
C. 24
D. 600

magnification is 15 x 40 = ?

To find the total magnification of a compound microscope, you need to multiply the magnification of the two lenses together. In this case, one lens has a magnification of 15 and the other lens has a magnification of 40.

Total magnification = Magnification of lens 1 x Magnification of lens 2

Total magnification = 15 x 40 = 600

Therefore, the total magnification of the microscope is 600, so the correct answer is option D: 600.
