Question

(x-3)³=27

 

Answer 1

`(x-3)^3=27`

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

`x-3=3`

`x=6`

Answer 2

\(\left(x-3\right)^3=27\)

nên x-3=3

hay x=6

Answer 3

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

\(x-3=3\)

\(x=6\)

Answer 4

(x-3)^3=3^3

TH1:x-3=3 =>x=6

TH2:x-3=-3 =>x=0

Answer 5

(x - 3)³ = 27

<=> (x - 3)³ - 3³ = 0

<=> (x - 3 - 3)(x - 3 + 3) = 0

<=> x(x - 6) = 0

<=> \(\left[{}\begin{matrix}x=0\\x-6=0\end{matrix}\right.\Leftrightarrow\left[{}\begin{matrix}x=0\\x=6\end{matrix}\right.\)
