1. Move the decimal point to the right until you have a number between 1 and 10. In this case, you'd move it five places to the right: 3.5065

2. Count the number of places you moved the decimal point. Since you moved it five places to the right, the exponent will be -5.

3. Write the number in the form of a x 10^b, where 'a' is the number you got after moving the decimal, and 'b' is the exponent.

Therefore, 0.000035065 in scientific notation is 3.5065 x 10^-5.
