Answer:

{m}^{2}

Step-by-step explanation:

\frac{ \sqrt{ {m}^{3} }  \times  {m}^{ \frac{2}{3} } }{ {m}^{ \frac{1}{6} } }  \\  \\  =  \frac{ { {m}^{ \frac{3}{2} } }  \times  {m}^{ \frac{2}{3} } }{ {m}^{ \frac{1}{6} } }  \\  \\  =  \frac{ {m}^{ \frac{3}{2}  +  \frac{2}{3} } }{ {m}^{ \frac{1}{6} } }  \\  \\ =  \frac{ {m}^{ \frac{3}{2}  +  \frac{2}{3} } }{ {m}^{ \frac{1}{6} } } \\  \\ =  \frac{ {m}^{ \frac{9 + 4}{2 \times 3}  }}{ {m}^{ \frac{1}{6} } } \\  \\ =  \frac{ {m}^{ \frac{13}{6}  }}{ {m}^{ \frac{1}{6} } }  \\  \\  =  {m}^{ \frac{13}{6} -  \frac{1}{6}  }  \\  \\  =  {m}^{ \frac{12}{6}   }  \\  \\  =  {m}^{2}
