To find the combined mass of the two skyscrapers, we simply need to add their masses together:
1. Mass of the first skyscraper: \( 2.2 \times 10^5 \) tons
2. Mass of the second skyscraper: \( 3.7 \times 10^5 \) tons
Now, we can add these two values:
\[
(2.2 \times 10^5) + (3.7 \times 10^5) = (2.2 + 3.7) \times 10^5 = 5.9 \times 10^5 \text{ tons}
\]
Thus, the combined mass of the two skyscrapers is:
\[
\boxed{5.9 \times 10^5} \text{ tons}
\]
1. Mass of the first skyscraper: \( 2.2 \times 10^5 \) tons
2. Mass of the second skyscraper: \( 3.7 \times 10^5 \) tons
Now, we can add these two values:
\[
(2.2 \times 10^5) + (3.7 \times 10^5) = (2.2 + 3.7) \times 10^5 = 5.9 \times 10^5 \text{ tons}
\]
Thus, the combined mass of the two skyscrapers is:
\[
\boxed{5.9 \times 10^5} \text{ tons}
