8 dividido por raiz de 6?

Answer 1

$\dfrac{8}{\sqrt{6}}\\ \\ =\dfrac{8\cdot \sqrt{6}}{\sqrt{6}\cdot \sqrt{6}}\\ \\ =\dfrac{8\sqrt{6}}{\left(\sqrt{6} \right )^{2}}\\ \\ =\dfrac{8\sqrt{6}}{6}\\ \\ =\dfrac{\diagup\!\!\!\!2\cdot 4\sqrt{6}}{\diagup\!\!\!\!2 \cdot 3}\\ \\ =\dfrac{4\sqrt{6}}{3}\\ \\ \\ \boxed{\dfrac{8}{\sqrt{6}}=\dfrac{4\sqrt{6}}{3}}$
