#9,009 * 10^4#


Numbers that are written in scientifit notation consists of 2 factors;
1) A number between 1 and 10
2) 10 to the power of anything

When you are converting a number to scientific notation, you place the period behind the first number, in this case 9.
Then you basically count the numbers that follow the period, to see what the exponent will be. In this case, there are 4 digits behind the period, and therefore you get #9,009* 10^4#.
