Step-by-step explanation: To find the exponent, we look at the expression again and see how much of the same number or fraction is repeated. Since the main number is 1/9 and there are 3 fractions repeating it, the exponent is
or 1/9 to the 3rd power.
<em>Down is a formula I made!</em>
Main number: 1/9
Repeating how many times: 3
Expression: 
Therefore, 1/9 to the 3rd power is 1/729.

<em>Note: The questioner did not ask for the answer. I wanted to add it anyway for future reasons.</em>

Answer:
3.3
Step-by-step explanation:
Find all the numbers and find the mean
The x means that there are that many of each number
1 + 1 + 2 + 3 + 3 + 4 + 4+ 5 + 5 + 5
33
We have to divide that by the total amount of numbers present
33/10 = 3.3
