Question

The amounts of e-waste generated in a region during two years were 14,200,000 tons and 10,700,000 tons. What was the total e-waste generated over these two years in the region, expressed in scientific notation?

Answer 1

Answer:

Using scientific notations, we can convert numerical values that are very large or very small into simpler forms using exponents. We should find the total e-waste generated over these two years in the region and then express it in scientific notation.

Answer and Explanation:

{eq}\begin{align*} \text{The amounts of e-waste generated during the first year}&=14,200,000\ \textrm{tons}\\[0.3 cm] \text{The amounts of e-waste...

Answer 2

Answer:

An easyer answer would be 2.49 ⋅ 107 tons

Explanation:

What you do is add 14,200,000 and 10,700,000 tons

14,200,000

+10,700,000

24,900,000

The rules of scientific notation are that the decimal point always has to be behind the first number. (you dont have to add the 0's)

$2.49x10^21$
