Answer 1

by
`\bf 7.96 *10^6` , the mass of the golden gate is larger than the Eiffel Tower

Explanation:

`\large \boldsymbol {} \sf 8,05\cdot 10^8-9,16\cdot 10^6 = 805\cdot 10^6-9,16\cdot 10^6 = \\\\ 10^6(805-9,16)=10^6\cdot 795,86 \\\\ Standart \ form \ 10^6\cdot 795,86 \approx 10^8\cdot 7,96 \ kg`

Answer 2

• 7.96 × 10⁸ kg more

Subtract the mass Eiffel Tower from the mass Golden Gate Bridge:

• 8.05 × 10⁸ - 9.16 × 10⁶ =
• (805 - 9.16) × 10⁶ =
• 795.84 × 10⁶ =
• 7.96 × 10⁸ kg
