1) Given
      \\4\sqrt {16 X^4 Y^{12}} \\
Now we solve this
\\4\sqrt {16 X^{4}Y^{12}} = 4*4 X^2 Y^6 = 16 X^2 Y^6\\
2) Given
       \\5\sqrt{12 x m^{3} }\\
    Now we solve this
    \\5\sqrt{12 x m^{3} } =10 m\sqrt{3 x m}\\
  3) Given
         \\\frac {5}{\sqrt {13}} \\ Â
   Now we solve this
   \\\frac{5}{\sqrt{13} } = \frac{5}{\sqrt{13} } *\frac{\sqrt {13} }   {\sqrt{13}=\frac{5\sqrt{13} }{13}\\
 4) Given
  \\(5 ab)^\frac{3}{2} \\
  Now we write in radical form
       \\(5 ab)^\frac{3}{2} = \sqrt{(5 ab)^3} \\
5) Given
      \\2\sqrt{54} -4\sqrt{24} \\
   now we solve this
     \\2\sqrt{54} - 4\sqrt{24} = 6\sqrt{6} - 8\sqrt{6} = -2\sqrt{6}\\
All I know is the answer for number one but it’s 2xy^2
