POR FVR ME AJUDEM!!!!

Answer 1

$\bullet~~M=\dfrac{18}{\sqrt{6}}$

$M=\dfrac{18}{\sqrt{6}}\cdot\dfrac{\sqrt{6}}{\sqrt{6}}$

$M=\dfrac{18\sqrt{6}}{6}$

$M=3\sqrt{6}$

$\bullet~~N=\dfrac{5}{2\sqrt{3}}$

$N=\dfrac{5}{2\sqrt{3}}\cdot\dfrac{\sqrt{3}}{\sqrt{3}}$

$N=\dfrac{5\sqrt{3}}{2\cdot3}$

$N=\dfrac{5\sqrt{3}}{6}$
