(6.3×10^9)+(4.3×10^11)=0.063×10^11
(4.3×10^11)=4.363×10^11
(6.3×10^9)+(4.3×10^11)=10.33×10^20=1.033×10^19
(6.3×10^9)×(4.3×10^11)=25.929×10^20=2.6×10^19
(6.03 x 10^9) + (4.3 x 10^11) = 4.363 x 10^11
Therefore, the total kilowatt-hours of electricity used during these two years was 4.363 x 10^11 kilowatt-hours.
