Question

sabendo que raiz d 2 +x=4raiz de 2 e raiz de 3 vezes y=5raiz de 6,calcule o valor de x+y.

Answer 1

$\sqrt{2+x} = 4 \sqrt{2} 2+x=(4 \sqrt{2} ) ^{2} 2+x=16.2 x=32-2=30 \sqrt{3y} =5 \sqrt{6} 3y=(5 \sqrt{6} ) ^{2} 3y=25.6 y=50$

$\sqrt{2+x} = 4 \sqrt{2} 2+x=(4 \sqrt{2} ) ^{2} 2 +x=16.2 x=32-2=30 \sqrt{3y} =5 \sqrt{6} 3y=(5 \sqrt{6} ) ^{2} 3y=25.6 y=50 x+y=80$
