Answer:

  2×10⁻¹

Step-by-step explanation:

The place values in our decimal number system can be thought of as powers of 10 that increase from 0 going left from the ones place. The sequence of powers of ten continues to decrease to the right of the decimal point. The first place right of the decimal point has a place value of 1/10, or 10^-1. The next place to its right has a place value of 1/100, or 10^-2.

So, the decimal number 2/10 = 0.2 is 2×1/10 = 2×10^-1.
