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
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.
