If a number is very large or very small then having a long string of 0s is likely to lead to errors.
No reason to put it in scientific notation but the result would be 2.59 x 10^4
4.83E1, but since this is just 48.3, there really is no reason to put it into scientific notation.
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.
There's no reason at all not to use scientific notation when it can be helpful. Consequently, it's widely used in situations where it's helpful.
There is no reason to put it in scientific notation. However, the result would be 3.158697 x 10^6
A good reason to learn scientific notation.
There is nothing to change. There is no reason to write 1.00054 in scientific notation. Technically, it could be written as 1.00054 × 100, but this is not normally done.
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. 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.
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.
To write 5.65 in scientific notation, move the decimal point one place to the left, which gives 0.565. Then, express the number as a product of a coefficient (between 1 and 10) and a power of 10. In this case, 0.565 can be written as 5.65 x 10^(-1) in scientific notation.
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.
