The mass of the Eiffel Tower is about 9.16 ⋅ 106 kilograms. The mass of the Golden Gate Bridge is 8.05 ⋅ 10*8 kilograms. Approximately how many more kilograms is the mass of the Golden Gate Bridge than the mass of the Eiffel Tower? Show your work and write your answer in scientific notation.
To find the difference in mass between the Golden Gate Bridge and the Eiffel Tower, we subtract the mass of the Eiffel Tower from the mass of the Golden Gate Bridge.
8.05 × 10^8 kg - 9.16 × 10^6 kg = 8.05 × 10^8 kg - 0.916 × 10^8 kg
To subtract these two numbers, we need to align the exponents.
8.05 × 10^8 kg - 0.916 × 10^8 kg = (8.05 - 0.916) × 10^8 kg
Now we can subtract the numbers.
7.134 × 10^8 kg
Therefore, the mass of the Golden Gate Bridge is approximately 7.134 × 10^8 kilograms more than the mass of the Eiffel Tower.
