You use scientific notation when it comes to "too large" or "too small" numbers. The purpose of this is to save some time to do the computation and also to make people's life easier to compute values instead of writing them out completely!
For instance, if we want to compute this expression:
1012301230912409 + 12901348093584542523
Then, we need to convert them into scientific notation!
In scientific notation - it would be 5.22x106
12,280,000 would be 1.228x107 in scientific notation.
778412020 in scientific notation is: 7.78412 × 108
Because if they did not, then it would not have been called scientific notation!
The scientific notation for 269000 would be 2.69 x 105.
14.6 in Scientific Notation = 1.46 x 101
A number such as this would not normally be expressed in scientific notation.
1.063x10^2 would be the scientific notation for the number.
It is: 9.3*10^-2 in scientific notation
It is: 3.9*10^7 in scientific notation
It is: 8.0*10^-4 in scientific notation
It is: 4.73829*10^5 in scientific notation
