Answer:
9th power of 10
Explanation:
To find the power of 10 in scientific notation. keep moving the decimal point to the left until you have only one digit to the left of the decimal point. Count the number of places you have moved the decimal point to the left and that is the exponent of 10 in scientific notation
5,708,100,000 does not have a decimal point but you can imagine a d.p at the end of the number
To get only one digit to the left of the d.p, you have to move it 9 places to the left until you get 5.7081
Therefore in scientific notation it is 5.7081 x 10⁹
The power is 9
