a: \(\Leftrightarrow10\sqrt{3x}-4\sqrt{3x}+8\sqrt{3x}=14\)
\(\Leftrightarrow14\sqrt{3x}=14\)
=>3x=1
hay x=1/3
b: \(\Leftrightarrow2\sqrt{x-5}+\sqrt{x-5}-\sqrt{x-5}=4\)
\(\Leftrightarrow2\sqrt{x-5}=4\)
=>x-5=4
hay x=9
c: \(\Leftrightarrow9\sqrt{x}-15-4\sqrt{x}+14=6\sqrt{x}-6\)
\(\Leftrightarrow6\sqrt{x}-6=5\sqrt{x}-1\)
\(\Leftrightarrow\sqrt{x}=5\)
hay x=25
d: \(\Leftrightarrow6\sqrt{x-2}-3\sqrt{x-2}=20+4\sqrt{x-2}\)
\(\Leftrightarrow-\sqrt{x-2}=20\)(vô lý)
