Answer 2

Answer:
C. 9.79 • 10^8

Step-by-step explanation:
In scientific notation, only keep the first digit, which is the 9 in this question.

*9*79,000,000

Insert a decimal after the first 9.
9.79000000

Starting from the rightmost end, drop all the zeroes until you reach a non-zero digit.
9.79

Multiply by ten to the power of the number of place values you started with after the first 9.

9.79 • 10^8
