Question

\(\sqrt{2x+3}=5\)

Answer 1

`sqrt{2x+3} =5`

`<=> 2x+3 =5^2=25`

`<=> 2x =25-3 = 22`

`x =22/2=11`

Answer 2

 2x+3=25     ( vì căn vế trái chuyển sang phải thành mũ)

2x=25-3

2x=22

x=11

Answer 3

\(\sqrt{2x+3}=5\)

\(\Leftrightarrow\sqrt{2x+3}^2=5^2\)

\(2x+3=25\)

\(2x=25-3\)

\(2x=22\)

\(x=11\)
