- Scientific notation (also known as Standard index notation) is a convenient way to write very small or large numbers.
- 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.
- 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.
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
