Answer:
The interpretation of given expression is "The quotient of the cube of the difference of 5x and 2 and the sum of x and 11".
Explanation:
The given expression is

a-b = Difference of a and b.
5x-2 = Difference of 5x and 2.
a+b = Sum of a and b.
x+11 = Sum of x and 11.
a³ = Cube of a.
= Cube of difference of 5x and 2.
a/b = Quotient of a and b.
= Quotient of the cube of the difference of 5x and 2 and the sum of x and 11.
Therefore the interpretation of given expression is "The quotient of the cube of the difference of 5x and 2 and the sum of x and 11".
