7 times the cube of the sum of x and 8

7 times the cube of the sum of x and 8

Take this algebraic expression in 3 parts:

1. The sum of x and 8 means we add 8 to x: x + 8
2. The cube of this sum means we raise the sum to the 3rd power: (x + 8)^3
3. 7 times this cubed sum means we multiply (x + 8)^3 by 7:

7(x + 8)^3
