- A.
7.7812 x 10^8
- B.
7.7812 x 12^8
- C.

- D.
7.7812 x 10^-8
Correct Answer
A. 7.7812 x 10^8Explanation
The correct answer is 7.7812 x 10^8. In scientific notation, a number is written in the form of a x 10^b, where "a" is a number between 1 and 10 (including 1 but not including 10), and "b" is an integer that represents the number of places the decimal point must be moved to obtain the original number. In this case, the original number is 778,120,000, which can be written as 7.7812 x 10^8 by moving the decimal point 8 places to the left.Rate this question:
