Ineed 1. simplify. 4√16x^4y^12 assume all variables are nonnegative. enter your answer in the box. 2. simplify 5√12xm^3 assume x and m are nonnegative. 10m^3√3x 10m√3xm 60m^3√x 60√xm^3 3. which expression is equal to 5/√13? 25/13 √5/13 5√13/13 √65/13 4. what is the expression in radical form? (5ab)3/2 ^3√5a^2b^2 √5a^3b^3 √125a^3b^3 ^3√25a^2b^2 5. which expression is equal to 2√54−4√24? −√6 −11√6 √6 −2√6 < < < < i chose this one, am i correct?

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}\\

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

the answer is c

hope this !

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
