Explanation :
Scientific notation : It is the representation of expressing the numbers that are too big or too small and are represented in the decimal form with one digit before the decimal point times 10 raise to the power.
For example :
5000 is written as![5.0\times 10^3](/tpl/images/0174/4843/57d48.png)
889.9 is written as![8.899\times 10^{-2}](/tpl/images/0174/4843/f8c71.png)
In this examples, 5000 and 889.9 are written in the standard notation and
and
are written in the scientific notation.
(a)![1.52\times 10^{-2}](/tpl/images/0174/4843/01ff2.png)
The standard notation is, 0.0152
(b)![7.78\times 10^{-8}](/tpl/images/0174/4843/50e6a.png)
The standard notation is, 0.0000000778
(c)![1\times 10^{-6}](/tpl/images/0174/4843/14519.png)
The standard notation is, 0.000001
(d)![1.6001\times 10^{3}](/tpl/images/0174/4843/eb7c0.png)
The standard notation is, 1600.1
