Answer 1

(7x)3+8 8 added to the cube of 7x

(7x+8)3 The cube of the sum of 7x and 8

7(x+8)3 7 times the cube of the sum of x and 8

7x3+8 8 added to 7 and x cubed

Answer 2

Answer with explanation:

1)

`7x^3+8`

we first cube a number x i.e.
`x^3`

and then multiply it by 7 and then finally add 8 to the resulting expression.

2)

`(7x+8)^3`

We first multiply the number x by 7 and then add 8 to it and then cube the resulting expression.

3)

`(7x)^3+8`

We first multiply x by 7 to get 7x and then cube the number and finally add 8 to it.

4)

`7(x+8)^3`

We add 8 to a number x to get x+8 and then cube it and finally multiply 7 to the resulting expression.
