$2.75 \times 10^{3} miles$

Here, we have $(0.000022)(125000000) miles=(2.2 \times 10^{-5} ) (1.25 \times 10^{8})miles$ Now, we need to use the separate product of powers property. $(0.000022)(125000000) miles=(2.2 \times 1.25 ) (10^{-5} \times 10^{8})miles$ ...(1) Equation (1) becomes: $(0.000022)(125000000) miles=(2.75 ) (10^{-5+8})$ This gives: $(0.000022)(125000000) miles=2.75 \times 10^{3} miles$
