Are you sure explain
I apologize for the confusion in my previous response. Let's calculate it again:
Electricity used in 1950 = 4.3 x 10^11 kilowatt-hours
Electricity used in 1902 = 6.03 x 10^9 kilowatt-hours
To find how many times more electricity was used in 1950 than in 1902, we divide the electricity used in 1950 by the electricity used in 1902:
(4.3 x 10^11) / (6.03 x 10^9) = 4.3 / 6.03 x 10^(11-9) = 0.711443 x 10^2 = 7.11443 x 10^1
So, the electricity used in 1950 was approximately 71.14 times more than in 1902. Expressing this in scientific notation, we get 7.11443 x 10^1.
Electricity used in 1950 = 4.3 x 10^11 kilowatt-hours
Electricity used in 1902 = 6.03 x 10^9 kilowatt-hours
To find how many times more electricity was used in 1950 than in 1902, we divide the electricity used in 1950 by the electricity used in 1902:
(4.3 x 10^11) / (6.03 x 10^9) = 4.3 / 6.03 x 10^(11-9) = 0.711443 x 10^2 = 7.11443 x 10^1
So, the electricity used in 1950 was approximately 71.14 times more than in 1902. Expressing this in scientific notation, we get 7.11443 x 10^1.

Is that correct
I apologize for the error in my previous responses. Let's recalculate it:
Electricity used in 1950 = 4.3 x 10^11 kilowatt-hours
Electricity used in 1902 = 6.03 x 10^9 kilowatt-hours
To find how many times more electricity was used in 1950 than in 1902, we divide the electricity used in 1950 by the electricity used in 1902:
(4.3 x 10^11) / (6.03 x 10^9) = (4.3 / 6.03) x 10^(11-9) = 0.7125748503 x 10^2 = 7.125748503 x 10^1
Therefore, the electricity used in 1950 was approximately 71.26 times more than in 1902. Expressing this in scientific notation, we get 7.125748503 x 10^1.
Electricity used in 1950 = 4.3 x 10^11 kilowatt-hours
Electricity used in 1902 = 6.03 x 10^9 kilowatt-hours
To find how many times more electricity was used in 1950 than in 1902, we divide the electricity used in 1950 by the electricity used in 1902:
(4.3 x 10^11) / (6.03 x 10^9) = (4.3 / 6.03) x 10^(11-9) = 0.7125748503 x 10^2 = 7.125748503 x 10^1
Therefore, the electricity used in 1950 was approximately 71.26 times more than in 1902. Expressing this in scientific notation, we get 7.125748503 x 10^1.
So it’s 7.13 •10^1?
Yes, that is correct. The electricity used in 1950 was approximately 7.13 x 10^1 times more than in 1902. Thank you for your patience.
