Scientific notations

1 answer

Scientific notation is a way of expressing numbers that are very large or very small. It is a shorthand method for writing numbers as a decimal multiplied by a power of 10. In scientific notation, a number is expressed in the form

a x 10^b

where

- a is a number between 1 and 10,
- b is an integer (positive or negative) denoting the power of 10.

For example,

- 1,000,000,000 can be written in scientific notation as 1 x 10^9
- 0.0000001 can be written in scientific notation as 1 x 10^-7

Scientific notation is commonly used in scientific and engineering fields where very large or very small numbers are encountered. It helps to simplify and compare numbers on a similar scale.
