Here's how we get there:

1. Move the decimal point to the left until there is only one non-zero digit to the left of the decimal point. In this case, we move it six places to the left.

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

3. Write the number with the decimal point in its new position, multiplied by 10 raised to the power you just calculated.
