Question

sendo x=2√50 +4√18 -3√32 e y=√2 calcule x:y

Answer 1

$\dfrac{ 2\sqrt{50} + 4 \sqrt{18} - 3 \sqrt{32}}{ \sqrt{2}} \\ \\ \\ \dfrac{ 2\sqrt{2 * 5^2} + 4 \sqrt{2 * 3^2} - 3 \sqrt{2^5}}{ \sqrt{2}} \\ \\ \\ \dfrac{ 2 * 5\sqrt{2} + 4 * 3 \sqrt{2} - 3 * 4 \sqrt{2}}{ \sqrt{2}} \\ \\ \\ \dfrac{ 10\sqrt{2} + 12 \sqrt{2} - 12 \sqrt{2}}{ \sqrt{2}}$

$\dfrac{ 10\sqrt{2} + \not12\sqrt{\not2} - \not12 \sqrt{\not2}}{ \sqrt{2}} \\ \\ \\ \dfrac{ 10\not\sqrt{\not2}}{ \not \sqrt{\not2}} \\ \\ \\ => 10$
