Пошаговое объяснение:

 \sqrt{ \frac{64}{4} }  =  \sqrt{16}  = 4 \\

 \frac{3}{ \sqrt{3}  +  \sqrt{2} }  -  \frac{2}{ \sqrt{3}  -  \sqrt{2} }  =  \frac{3 \sqrt{3}  - 3 \sqrt{2} - 2 \sqrt{3} - 2 \sqrt{2}   }{1}  =  \sqrt{3}  -  5\sqrt{2}  \\

 \frac{ {3}^{ - 2}  \times  {5}^{ - 3} }{ {15}^{ - 3} }  =  \frac{ {3}^{ - 2} }{ {3}^{ - 3} }  = 3 \\

|-5.5|/|1.1|=5.5/1.1=5
