To find the number of households the power station can serve, we need to divide the total electricity generated by the electricity used per household.
2.496 x 10^10 kWh ÷ 1.04 x 10^4 kWh
When dividing in scientific notation, we subtract the exponents and divide the coefficients:
2.496 ÷ 1.04 = 2.4
The exponent of the numerator is 10 and the exponent of the denominator is 4. Since we are dividing, we subtract the exponents:
10 - 4 = 6
Therefore, the answer is 2.4 x 10^6 households.
