Scientific notation: a form of presenting large or small numbers in a simpler form.
• The ,exponent, is ,positive, if the number is very ,large.
,• The ,exponent ,is ,negative ,if the number is very ,small.
,• The ,base ,is ,always 10.
In our case, as our number is a large one, we will have a positive exponent, and we have to count the spaces we will move the point to know which will be our final result:
If we count the spaces, we will see that there are 8, as shown in the image above.
Then, our number is:
[tex]408,000,000=4.08\times10^8[/tex]Answer:
[tex]=4.08\times10^8[/tex]
