Answer:
Distance, size, etc.
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
