Where is scientific notation used in the real-world?

Distance, size, etc.

Step-by-step explanation:

We know that scientific notation is used to write extremely large or extremely small numbers, correct?

So think of scenarios where you need to express a very large or very small numbers.

For example, the distance between the sun and Pluto in miles. That would be a very large number, it is around 3.67*10^9

Or the size of a cell but in meters. That would be a very small number, I estimate about 1 x 10^-6 in scientific notation
