Would you rather write 6000000000000000000 X 6000000000000000000 = 36000000000000000000000000000000000000 or 6E18 X 6E18 = 3.6E37? Advantage: scientific notation.
It has no advantage.
There is nothing to change. There is no advantage or reason to write 2.33 in scientific notation. It could be written as 2.33 × 100, but this is not normally done.
The advantage of expressing numbers in scientific notation is that they are more compact.
There's nothing to change here. There is no advantage or reason to write 7.2 in scientific notation. Technically, however, it could be written as 7.2 × 100, but this is not normally done.
There's nothing to change here. There is no advantage or reason to write 8.2576 in scientific notation. Technically, however, it could be written as 8.2576 × 100, but this is not normally done.
There's nothing to change. There is no advantage or reason to write 1.60 in scientific notation. It could be written as 1.60 × 100, but this is not normally done.
Less digits are needed for very large numbers
There's nothing to change here. There is no advantage or reason to write -4.3 in scientific notation. Technically, however, it could be written as -4.3 × 100, but this is not normally done.
An advantage of using the scientific notation is that scientists have to use large and small numbers and this helps them by showing the number in a smaller way.
It is 8.9*10^-5 in scientific notation
It is "(scientific notation)".
This number in scientific notation is 9.8x10-5.
