  1. $\sqrt{27}+\sqrt{48}-\sqrt{108}-\sqrt{12}$
    $=3\sqrt{3}+4\sqrt{3}-6\sqrt{3}-2\sqrt{3}$
    $=-\sqrt{3}$
     

  2. Answer
    \sqrt{27} + \sqrt{48} – \sqrt{108} – \sqrt{12}
    = 3\sqrt{3} + 4\sqrt{3} – 6\sqrt{3} – 2\sqrt{3}
    = 7\sqrt{3} – 6\sqrt{3} – 2\sqrt{3}
    = \sqrt{3} – 2\sqrt{3}
    = -\sqrt{3}
