ANSWER


6.84\times 10^9



EXPLANATION.


To write in scientific notation means , we write in form,


k\times 10^n


Where n is an integer and


1\le k\:


The given number is,


6,840,000,000


We move the decimal point backward to obtain our k, the n here is 9, because we moved backward 9 times.



This implies that,



6,840,000,000=6.84\times 10^9


The correct answer is D
