​

Answer 1

Resposta:

Explicação passo-a-passo:

Temos que

$\frac{3}{2}+\sqrt{90}-\frac{1}{4}\sqrt{250}-\frac{1}{4}\sqrt{10}=>\frac{3}{2}+3\sqrt{10}-\frac{1}{4}5\sqrt{10}-\frac{1}{4}\sqrt{10}=>\frac{3}{2}+3\sqrt{10}-\frac{5}{4}\sqrt{10}-\frac{1}{4}\sqrt{10}=>\frac{2.3+4.3\sqrt{10}-5\sqrt{10}-\sqrt{10}}{4}=>\frac{6+12\sqrt{10}-6\sqrt{10}}{4}=>\frac{6+6\sqrt{10}}{4}=>\frac{3+3\sqrt{10}}{2}$
