Multiply the distances: (5.8×107)⋅(4.5×1010) = (5.8×4.5)⋅(107+10)=26.1×1017=2.61×1018
km
Multiply the distances: (5.8×107)⋅(4.5×1010) = (5.8×4.5)⋅(107+10)=26.1×1017=2.61×1018
km

Add the distances together: (5.8×107)+(4.5×1010) = 10.3×1017=1.03×1018

Subtract the distances by getting the same power of 10: (4.5×1010)−(5.8×107) =(4.5×1010)−(0.0058×1010)=4.49×1010

Divide the distances: 4.5×10105.8×107=0.78×103 =7.8×102
km

The correct response is:

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)=4.4942×10^10 km

Therefore, Neptune is further from the sun than Mercury by approximately 4.4942×10^10 km.
