Scientific Notation (Standard Form)

1. Scientific notation (also known as Standard index notation) is a convenient way to write very small or large numbers.
2. In this notation, numbers are separated into two parts, a real number with an absolute value between 1 and 10 and an order of magnitude value written as a power of 10.
3. Physical quantities that are very big or very small need to be written in the standard form so that it is neat, simple and easy to read.

Example

1. 2,600 = 2.6 x 10³
2. 75,300,000 = 7.53 x 10⁷
3. 0.00023 = 2.3 x 10^-4
4. 0.00000004121 = 4.121 x 10^-8
