5.779 x 10^-8 =0.00000005779
Step-by-step explanation:
The E-8 at the end means the number is multiplied by 10^-8.
So 5.779E-8=5.779 x 10^-8
A negative power means move the decimal place that many places to the left
So 5.779 x 10^-8 =0.00000005779
The answer is D, because you move to the right of the decimal to see if that number is 5 or above. Then you round up, (to 86). :) Hope this was helpful.
