Question

trừ A,B ra thì giúp toi mấy cái còn lại nha:> tks

Answer 1

\(M=\sqrt{\dfrac{\left(11+\sqrt{96}\right)^2}{121-96}}+\sqrt{\dfrac{\left(11-\sqrt{96}\right)^2}{121-96}}\\ M=\dfrac{11+\sqrt{96}}{5}+\dfrac{11-\sqrt{96}}{5}=\dfrac{22}{5}\)

Answer 2

\(D=\dfrac{2}{\sqrt{3}-1}-\dfrac{3}{2-\sqrt{3}}-\dfrac{6}{3-\sqrt{3}}\)

\(=\sqrt{3}+1-6-3\sqrt{3}-3-\sqrt{3}\)

\(=-8-3\sqrt{3}\)
