Here's how to convert it:

1. Move the decimal point to the right until you have a number between 1 and 10. In this case, we move it five places to the right, giving us 3.007.

2. Count the number of places you moved the decimal. We moved it five places.

3. If you moved the decimal to the right, the exponent is negative. Since we moved it to the right, the exponent is -5.

Therefore, 0.00003007 in exponential notation is 3.007 x 10⁻⁵.
