Question

Rút gọn giúp tớ các câu này với nhé

Answer 1

g: \(=\dfrac{\sqrt{10}\left(\sqrt{5}+\sqrt{2}\right)\cdot\sqrt{3}\left(1-\sqrt{6}\right)}{\sqrt{30}}\)

\(=\left(\sqrt{5}+\sqrt{2}\right)\left(1-\sqrt{6}\right)\)

h: \(=\dfrac{\sqrt{35}\left(\sqrt{5}-4+\sqrt{7}\right)}{\sqrt{35}}=\sqrt{5}-4+\sqrt{7}\)

i: \(=\dfrac{\sqrt{24}\left(3-\sqrt{2}\right)+\left(3-\sqrt{2}\right)}{2\sqrt{6}+1}=3-\sqrt{2}\)

j: \(=\dfrac{5\sqrt{3}\left(2\sqrt{6}+1-9\right)}{\sqrt{3}\left(\sqrt{6}-4\right)}=\dfrac{5\left(2\sqrt{6}-8\right)}{\sqrt{6}-4}=5\cdot2=10\)
