Questions and Answers

1.

- 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 10^8

Explanation
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.

In scientific notation, the number is expressed as a decimal between 1 and 10 (in this case, 5.3) multiplied by a power of 10 (in this case, -2). The negative exponent indicates that the decimal point is shifted two places to the left, making the number smaller.
