Question

Convert 65000000 to a scientific notation

6.5 • 10^6
6.5 • 10^7
6.5 • 10^-6
6.5 • 10^-7

Answer 1

The answer is B because you move the decimal point in 6.5 seven places to the right so it’s gonna be the second one....

Answer 2

The answer is B. In order to solve this, you have to start at the point from 6.5 and then count how many spots you go down until you reach the end. I counted 7 spots to the right which means there were 6 0’s. The answer can not be negative because it was not .65000000
