Answer 1

`(2+x)^3 - 23 = 4`

`(2+x)^3 = 4+23`

`(2+x)^3 = 27`

`=> 2+x=3`

`x=3-2`

`x=1`

Answer 2

`(2+x)^3-23=4`

`=>(2+x)^3=4+23`

`=>(2+x)^3=27`

`=>(2+x)^3=3^3`

`=>2+x=3`

`=>x=3-2`

`=>x=1`

Answer 3

Answer 4

`(2+x)^3-23=4`

`=> (2+x)^3=4+23`

vậy `x=1`

Answer 5

\(\left(2+x\right)^3-23=4\)

\(\Rightarrow\left(2+x\right)^3=4+23\)

\(\Rightarrow\left(2+x\right)^3=27\)

\(\Rightarrow\left(2+x\right)^3=3^3\)

\(\Rightarrow2+x=3\)

\(\Rightarrow x=3-2\)

\(\Rightarrow x=1\)

Answer 6

(2+x)^3=4+23=27
