To find out how many households can be served by the power station, we need to divide the total electricity generated by the power station by the electricity used by an average household.
Total electricity generated by the power station = 2.496 × 10¹⁰ kWh
Electricity used by an average household = 1.04 × 10⁴ kWh
To divide these two values, we subtract the exponents of 10 and divide the coefficients:
(2.496 × 10¹⁰) / (1.04 × 10⁴) = (2.496 / 1.04) × 10¹⁰-⁴ = 2.4 × 10⁶
Therefore, the power station can serve 2.4 × 10⁶ households.
An average American household uses about
1.04 × 10⁴ kWh (kilowatt hours) of electricity a year. If a power station generates 2.496 × 10¹⁰ kWh per year, how many households can it serve? Write your answer in scientific notation, expressed to the exact decimal
