Multiply the distances: (5.8×10^7)⋅(4.5×10^10)=(5.8×4.5)⋅(10^(7+10))=26.1×10^17=2.61×10^18 km
Subtract the distances by getting the same power of 10: (4.5×10^10)−(5.8×10^7) =(4.5×10^10)−(0.0058×10^10)=4.49×10^10 km
Add the distances together: (5.8×10^7)+(4.5×10^10) = 10.3×10^17=1.03×10^18 km
Divide the distances: 4.5×10^10/5.8×10^7=0.78×10^3 =7.8×10^2 km
