Here's how to get there:

1. Move the decimal point to the right until you have a number between 1 and 10. In this case, we move it 11 places to the right.

2. Count the number of places you moved the decimal. This is the exponent of 10.

3. If you moved the decimal to the right, the exponent is negative. If you moved it to the left, the exponent is positive.

Therefore, 0.00000000003 becomes 3 x 10^-11.
