Scientific notation uses short-hand for long numbers, writing the numbers in a standard form of a decimal number greater or equal to 1 and less than 10 multiplied by a power of 10, whereas ordinary notation just writes the number as one would every number. It helps to avoid errors when there could be a lot of zeros and makes the writing of numbers more compact.. As an example, 573,000,000,000,000 would be written as 5.73 x 10^14.
This also allows numbers to be rounded as necessary without a bunch of 0s. For example, 573,261,578,357,198 to three significant figures would be 573,000,000,000,000 which would be written as 5.73 x 10^14 (as above).
Ordinary notation is where the numbers are laid, or written out. Scientific notation is a short handed version with numbers that indicate the amount of zeroes behind the end of the numbers.
Ordinary decimal notation
For the same reason that numbers in ordinary notation need computing.
This provides a convenient and compact way to write very large or very small numbers.
It is 8.9*10^-5 in scientific notation

Ordinary decimal notation
Less digits are needed as for example 1,000,000,000 is 1.0*109 in scientific notation
The answer depends on what the wave length is in ordinary numbers! For example, radio waves can have a wavelength of 1 metre: in scientific notation, that is 1!

9.21x103 in ordinary decimal notation = 9,210
Scientific notation is a way to express either a very large, or a very small number.10x5.34 is an example of scientific notation. So, move the decimal point to the right (since there is a positive exponent). It then becomes 53,000.If there is a negative exponent, move the decimal point to the left instead of the right. 10x4.6-3 would become 0.0046.
This provides a convenient and compact way to write very large or very small numbers.
It is 8.9*10^-5 in scientific notation
It is "(scientific notation)".
It is: 2.7*10^0 in scientific notation
This number in scientific notation is 9.8x10-5.
