1. Move the decimal point to the right until you have a number between 1 and 10. In this case, we need to move it 8 places to the right.
2. Count the number of places you moved the decimal point. This is the exponent of 10. Since we moved it 8 places to the right, the exponent is -8.
3. Write the number with the decimal after the first digit, followed by "x 10" and the exponent you calculated.
Therefore, the scientific notation of 0.000000068 is 6.8 x 10⁻⁸.
