Answer 1

Answer:

$7.96 *10^8kg$

Step-by-step explanation:

Given

$Eiffel = 9.16 * 10^6\ kg$

$Golden\ Gate =8.05 * 10^8kg$

Required

Determine the difference in mass

This is calculated by subtracting the mass of Eiffel tower from the mass of Golden gate bridge

$Difference = Golden\ Gate - Eiffel$

$Difference = 8.05 * 10^8 - 9.16 * 10^6$

Express $10^8$ as $10^6 * 10^2$

$Difference = 8.05 * 10^2*10^6 - 9.16 * 10^6$

Express $10^2$ as $100$

$Difference = 8.05 * 100*10^6 - 9.16 * 10^6$

$Difference = 805 *10^6 - 9.16 * 10^6$

Factorize:

$Difference = (805- 9.16) * 10^6$

$Difference = 795.84 * 10^6$

Factorize the decimal number

$Difference = 7.9584 *10^2 * 10^6$

$Difference = 7.9584 *10^8$

Approximate:

$Difference = 7.96 *10^8$
