Answer :
8 x 10^8 = 800,000,000
In Scientific Notation, your goal is to get your the number you're multiplying by 10 (8 in this case) to be between 0 and 10. Therefore, you would NOT have 80 x 10^7 because 80 is not between 0 and 10.
The term is really first expressed as 800000000.0. Move 8 decimal places to the left from the starting point and write out:
8.0 x 108
And that's what your answer is :3
8.0 x 108
And that's what your answer is :3
