Refractive power#=1.3xx10^(-4)" m"^-1#.

Explanation:

The refractive power of a lens is given by the inverse of the focal length: #1/f#.

Therefore, we have #1/80# inverse centimeters.

The SI unit of refractive power is the diopter, however, which is equivalent to #m^-1#. So we might instead write that the refractive power of the lens is #~~1.3xx10^(-4)" m"^-1#.
