2,0.6295 * (10 to the sixth power)

Take the second topic as an example: 2 is a decile, 9 is a percentile and 5 is a thousandth, so if you want to be accurate to one ten thousandth, you only need to move the decimal point forward by one place, which becomes 0.6295* 10, so the answer is 0.6295*( 10 to the sixth power).
