Answer 1

To find the combined mass of the two skyscrapers, we will add their masses together.

1. The mass of the first skyscraper is \(2.2 \times 10^5\) tons.
2. The mass of the second skyscraper is \(3.7 \times 10^5\) tons.

Now, we add these two quantities:

\[ (2.2 \times 10^5) + (3.7 \times 10^5) = (2.2 + 3.7) \times 10^5 = 5.9 \times 10^5 \]

Thus, the combined mass of the two skyscrapers is \(5.9 \times 10^5\) tons.
