Here's how we get there:
1. Move the decimal point to the left until you have a number between 1 and 10. In this case, we move it six places to the left, resulting in 6.23.
2. Count the number of places you moved the decimal point. This number becomes the exponent of 10. Since we moved it six places, the exponent is 6.
3. Combine the number and the exponent to get the scientific notation: 6.23 x 106.
