0.000000084

we need to move the decimal 8 places to the right

8.4* 10^-8

Hi There!

Eliminate C and D because when you are putting numbers into scientific notation the number can not be greater than 10.

8.4 x 10^-7 is the same as dividing 8.4 by 10 seven times which equals 0.00000084 which is not equal to the decimal form given in the question.

8.4 x 10^-8 = 0.000000084

Answer: B) 8.4 x 10−8

Hope This Helps :)
