To find out how many times more electricity was used in 1950 than in 1902, we need to divide the amount used in 1950 by the amount used in 1902:
4.3x10^11 / 6.03x10^9 = 71.29
Therefore, the electricity used in 1950 was approximately 71.29 times more than in 1902.
Expressed in scientific notation, this would be 7.13x10^1.
the use of electricity in the US in 1902 was 6.03x10^9 kilowatt-hours
the use of electricity in the US in 1950 was 4.3x10^11 kilowatt hours.
how many time more was the electricity used in 1950 than 1902 express your answer in scientific notation
