Question

mọi người giúp mình với ạ,mình cảm ơn

Answer 1

a: \(=\dfrac{2\sqrt{2}+3\sqrt{3}}{8-27}=\dfrac{-2\sqrt{2}-3\sqrt{3}}{19}\)

b: \(=\sqrt{\dfrac{\left(3-\sqrt{5}\right)^2}{4}}=\dfrac{3-\sqrt{5}}{2}\)

c: \(=\dfrac{\sqrt{8}\left(\sqrt{5}+\sqrt{3}\right)}{2}=\sqrt{2}\left(\sqrt{5}+\sqrt{3}\right)\)

d: \(=\sqrt{\dfrac{\left(2-\sqrt{3}\right)^2}{1}}=2-\sqrt{3}\)
