Question

( 3x - 2 )³ =2.32

Answer 1

`(3x-2)^3 = 2.32`

`=> (3x-2)^3 = 64`

`=> (3x-2)^3 = 4^3`

`=>  3x-2      = 4`

`=>  3x         = 4 + 2`

`=>  3x         = 6`

`=>    x         = 6 : 3`

`=>    x         = 2`

Answer 2

\(\left(3x-2\right)^3=64\)

\(3x-2=4\)

\(3x=6\)

\(\Rightarrow x=2\)

Answer 3

\(\left(3x-2\right)^3=2.32\)

\(\left(3x-2\right)^3=64\)

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

\(3x-2=4\)

\(3x=4+2\)

\(3x=6\)

\(x=6:3\)

\(x=2\)

Answer 4

=>(3x-2)³=64

=>(3x-2)³=4³

=>3x-2=4

=>3x=4+2

=>3x=6

=>x=6:3

=>x=2

Vậy x=2
