Thực hiện phép tính \(\left( {\sqrt {12} - \sqrt {75} + \sqrt {48} } \right):\sqrt 3 \).

Ta có: \(\left( {\sqrt {12} - \sqrt {75} + \sqrt {48} } \right):\sqrt 3 = \frac{{\left( {\sqrt {12} - \sqrt {75} + \sqrt {48} } \right)}}{{\sqrt 3 }} = \frac{{\sqrt {12} }}{{\sqrt 3 }} - \frac{{\sqrt {75} }}{{\sqrt 3 }} + \frac{{\sqrt {48} }}{{\sqrt 3 }}\)

\( = \sqrt {\frac{{12}}{3}} - \sqrt {\frac{{75}}{3}} + \sqrt {\frac{{48}}{3}} = \sqrt 4 - \sqrt {25} + \sqrt {16} = 2 - 5 + 4 = 1\).
