-3.0 D. What is the power of the combination of the two lenses?

To find the power of the combination of two lenses placed in contact, we use the formula:

P = P1 + P2 - (d/P1P2)

Where P is the power of the combination, P1 and P2 are the powers of the individual lenses, and d is the distance between the two lenses. In this case, the lenses are in contact, so d = 0.

Plugging in the values given, we get:

P = 2.0 D + (-3.0 D) - (0/2.0 D x (-3.0 D))

P = -1.0 D

Therefore, the power of the combination of the two lenses is -1.0 D.
