+118613 what is 0.0000686 in scientific notation
It is a very little number so the index will be negative.
You want just one non zero digit in front of the point so the number part will be 6.86
You had to jump the point over 4 zeros and the 6 to get it to its new position. That is 5 jumps altogether. So the power will be 5 BUT remember it is negative!
\(0.0000686=6.86\times 10^{-5}\)
