Lets use algebra and simplify:

<u>Note in the above steps:</u> dividing by a fraction is same as multiplying by its reciprocal
The first answer choice is the correct one.
ANSWER: 
The sum (addition) of -2 and 3 times (3 ·) a number (n)
-2 + 3n
32^3/5 = 8
64^2/3 = 16
81^1/4 = 3
49^1/2 = 7
125^2/3 = 25
now just put them in order from the smallest value to the largest
7/24 I hope this helps you
