​

Answer 1

Resposta:

Explicação passo-a-passo:

Temos que

$(\frac{20\sqrt{10}+10\sqrt{18}}{2\sqrt{2}})=\frac{20\sqrt{10}}{2\sqrt{2}}+\frac{10\sqrt{18}}{2\sqrt{2}}=\frac{20\sqrt{10}\sqrt{2}}{2\sqrt{2}\sqrt{2}}+\frac{10\sqrt{18}\sqrt{2}}{2\sqrt{2}\sqrt{2}}=\frac{20\sqrt{20}}{2.2}+\frac{10\sqrt{36}}{2.2}=\frac{20\sqrt{2^{2}.5}}{4}+\frac{10.6}{4}=\frac{20.2\sqrt{5}}{4}+\frac{60}{4}=10\sqrt{5}+15$
