1. Move the decimal point to the right until you have a number between 1 and 10. In this case, we need to move the decimal point two places to the right: 2.01
2. Count the number of places you moved the decimal point. We moved it two places.
3. If you moved the decimal point to the right, the exponent will be negative. If you moved it to the left, the exponent would be positive.
4. Write the number in the form of a x 10^b where 'a' is the number between 1 and 10, and 'b' is the exponent.
Therefore, the scientific notation of 0.0201 is 2.01 x 10^-2.
