Answer:

1.25 x
10^2

Explanation:

Move the decimal point to make 125.0 a new number between 1 and 10. Because our number is greater than 10, we move the decimal point to the left. Drop any trailing zeroes. Keep track of how many times we move the decimal point. 125.0 -> 1.25. Our new number is 1.25. We moved the decimal point 2 times.
