To find the combined mass of the two skyscrapers, we simply add their masses together.
Mass of first skyscraper: 2.2x10^5 tons
Mass of second skyscraper: 3.7x10^5 tons
Combined mass = 2.2x10^5 + 3.7x10^5
To add these numbers, we first need to ensure that the exponents are the same. Since both numbers are already in scientific notation, we can directly add them.
Combined mass = (2.2 + 3.7) x 10^5
= 5.9 x 10^5
In scientific notation with one decimal place, the combined mass of the two skyscrapers is 5.9x10^5 tons.
A skyscraper has a mass of 2.2x10^5 tons. Another skyscraper in the same town has a mass of3.7x10^5 tons what is the combined mass in the tons of the two skyscrapers you scientific notation to express your answer in one decimal place
