\(\sqrt{4x-5}=\sqrt{3}\) (ĐKXĐ: \(x\ge\dfrac{5}{4}\))
\(\Rightarrow4x-5=3\)
\(\Rightarrow4x=8\)
\(\Rightarrow x=2\)(thỏa mãn)
Vậy x = 2

\(\sqrt{4x-5}=\sqrt{3}\left(ĐKXĐ:x\ge\dfrac{5}{4}\right)\)
\(\Rightarrow4x-5=3\)
\(\Leftrightarrow4x=8\)
\(\Leftrightarrow x=2\left(tm\right)\)
Vậy \(S=\left\{2\right\}\)
ĐKXĐ: x>=5/4
\(\sqrt{4x-5}=\sqrt{3}\)
=>4x-5=3
=>4x=8
=>x=8/4=2(nhận)
