0.073 would be written as
Explanation:
Scientific notation uses multiplication or division of a number by 10s to express a number without taking up too much space.
For example we express large numbers like this:
3000000000=3⋅108
The number above, 300 million, is simply the same as taking 3 and multiplying it by 10 8 times. This is exactly what
300000000=3×10⋅10⋅10⋅10⋅10⋅10⋅10⋅10
On the other hand, we can express very small numbers by dividing by ten, as in your example. We tell others that we are dividing by ten by using a negative exponent.
For example:
3⋅102=3⋅10⋅10
While
3⋅10−2=310⋅10
