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 six places to the right: 0.0000054 becomes 5.4.
2. Count the number of places you moved the decimal. Since we moved it six places to the right, our exponent is -6.
3. Write the number in scientific notation. This is the form "a x 10b", where 'a' is the number between 1 and 10, and 'b' is the exponent. Therefore, the scientific notation of 0.0000054 is 5.4 x 10-6.
