Question

I NEED HELP

Answer 1

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}} \\  

     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}\\

Answer 2

All I know is the answer for number one but it’s 2xy^2
