Question

Racionalize:

a) 8/3√5

b) 6/√2

Answer 1

Resposta:

$a)\dfrac{8\sqrt{5}}{15}$

$b)3\sqrt{2}$

Explicação passo-a-passo:

$a)\dfrac{8}{3\cdotz\sqrt{5}}=\dfrac{8}{3\cdotz\sqrt{5}}\cdot\dfrac{\sqrt{5}}{\sqrt{5}}=\dfrac{8\sqrt{5}}{3\cdot5}=\dfrac{8\sqrt{5}}{15}\\\\b)\dfrac{6}{\sqrt{2}}=\dfrac{6}{\sqrt{2}}\cdot\dfrac{\sqrt{2}}{\sqrt{2}}=\dfrac{6\sqrt{2}}{2}=3\sqrt{2}$
