Question

The amounts of plastic waste generated in a region during two years were 32,400,000 tons and 20,300,000 tons. What was the total plastic waste generated over these two years in the region, expressed in scientific notation?

Answer 1

Just assume this two numbers 

32400000 +
20300000
-----------------
52700000 what expressed in scientific notation will be 5,27 * 10^7

hope this will help you 

Answer 2

Answer: $5.27\times10^{7}$ tons.

Step-by-step explanation:

The scientific notation is a method to write a very large or a very small number in the product of a decimal form of number [generally lies between 1 and 10] and powers of ten.

Given : The amounts of plastic waste generated in a region during two years were 32,400,000 tons and 20,300,000 tons.

Then the total amount of plastic waste generated in a region during two years is given by :-

$32,400,000+20,300,000=52,700,000$

In scientific notation , $52,700,000=5.27\times10^{7}$

Hence, the total plastic waste generated over these two years in the region = $5.27\times10^{7}$ tons.
