* Move the decimal point to the left until you have a number between 1 and 10. In this case, we move it two places to the left, giving us 9.8835.

* Count the number of places you moved the decimal. We moved it two places.

* Multiply the new number by 10 raised to the power of the number of places you moved the decimal. Since we moved it two places to the left, the exponent is positive 2.

Therefore, 988.35 written in scientific notation is 9.8835 x 10².
