Here's how we get there:

1. Move the decimal point to the right until there's only one non-zero digit to the left of the decimal point. We move it six places to the right.

2. Count the number of places you moved the decimal. This is the exponent of 10. Since we moved it to the right, the exponent is negative.

3. Write the number with the decimal point after the first non-zero digit, multiplied by 10 raised to the power you calculated.
