How do you do <br><br> x√x = √216<br><br> you have to solve for x and it should equal 6
PIT_PIT [208]

Answer:

x \sqrt{x}  =  \sqrt{216}

square both sides:

{(x \sqrt{x}) }^{2}  =  {( \sqrt{216}) }^{2}

solve the roots:

( {x}^{2} .x) = 216 \\  {x}^{3}  = 216

take a cube root on both sides:

\sqrt[3]{ {x}^{3} }  =  \sqrt[3]{216}

solve the cube root:

x = 6
