Question

(3x - 2)²= 64

 

Answer 1

(3x-2)\(^2\)=64\(\Rightarrow\)\(3x-2=8\Rightarrow3x=10\Rightarrow x=\frac{10}{3}\)hoặc\(3x-2=-8\Rightarrow3x=-6\Rightarrow x=-2\)

Answer 2

(3X - 2)² = 64
<=> (3X - 2)² = 8²

<=> 3X - 2 = 8
<=> 3X= 10
<=> X = 10/3

Answer 3

(3x-2)^2 = 64

(3x-2)^2 = 8^2

=> 3x-2 = 8

3x=10 

X= 10/3
