Question

(2x-1)^3=125

 

Answer 1

\(\left(2x-1\right)^3=125\)

\(\Rightarrow2x-1=5\Rightarrow2x=6\Rightarrow x=3\)

Answer 2

(2x - 1)³ = 125

<=> (2x - 1)³ = 5³

<=> 2x - 1 = 5

<=> 2x = 6

<=> x = 3

Answer 3

\(\Rightarrow2x-1=5\)

\(\Rightarrow2x=6\)

\(\Rightarrow x=3\)

Answer 4

(2x-1)^3 = 5^3
(2x-1) = 5
2x = 5 + 1
2x = 6
x = 6 :2
x= 3

Answer 5

⇒ 2 x − 1 = 5

⇒ 2 x = 6

⇒ x = 3

Answer 6

\(( 2x - 1 ) ^3 = 125 \) 

\(( 2x - 1 ) ^3 = 5^3 \) 

➝ \(2x - 1 = 5 \) 

➝ \(2x = 6 \) 

➝ \(x = 3 \) 

Vậy \(x = 3 \)
