0.125340000

First of all all trailing 0s after a decimal point have no value so

0.125340000=0.12534

Now you have to put one non-zero number in front of the point so that would be 1.2534

0.12534 is a llittle number - less than 1 so the index (exponent) will be negative.

To move the point from 0.12543 to 1.2543 you had to jump the point over 1 number (the 1)

so the answer is 1.2534 x 10^{-1}
