mik nghĩ là C nha bn

\(A=\dfrac{\sqrt{20}-6}{\sqrt{14-6\sqrt{5}}}-\dfrac{\sqrt{20}-\sqrt{28}}{\sqrt{12-2\sqrt{35}}}=\dfrac{-2\left(3-\sqrt{5}\right)}{\sqrt{\left(3-\sqrt{5}\right)^2}}+\dfrac{2\left(\sqrt{7}-\sqrt{5}\right)}{\sqrt{\left(\sqrt{7}-\sqrt{5}\right)^2}}\)

\(=\dfrac{-2\left(3-\sqrt{5}\right)}{3-\sqrt{5}}+\dfrac{2\left(\sqrt{7}-\sqrt{5}\right)}{\sqrt{7}-\sqrt{5}}=-2+2=0\)

\(B=\sqrt{\dfrac{\left(9-4\sqrt{3}\right)\left(6-\sqrt{3}\right)}{\left(6-\sqrt{3}\right)\left(6+\sqrt{3}\right)}}-\sqrt{\dfrac{\left(3+4\sqrt{3}\right)\left(5\sqrt{3}+6\right)}{\left(5\sqrt{3}-6\right)\left(5\sqrt{3}+6\right)}}\)

\(=\sqrt{\dfrac{66-33\sqrt{3}}{33}}-\sqrt{\dfrac{78+39\sqrt{3}}{39}}=\sqrt{2-\sqrt{3}}-\sqrt{2+\sqrt{3}}\)

\(=\dfrac{1}{\sqrt{2}}\left(\sqrt{4-2\sqrt{3}}-\sqrt{4+2\sqrt{3}}\right)=\dfrac{1}{\sqrt{2}}\left(\sqrt{\left(\sqrt{3}-1\right)^2}-\sqrt{\left(\sqrt{3}+1\right)^2}\right)\)

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

a) Ta có: \(A=\dfrac{\sqrt{10}-3\sqrt{2}}{\sqrt{7-3\sqrt{5}}}-\dfrac{\sqrt{10}-\sqrt{14}}{\sqrt{6-\sqrt{35}}}\)

\(=\dfrac{2\sqrt{5}-6}{3-\sqrt{5}}-\dfrac{2\sqrt{5}-2\sqrt{7}}{\sqrt{7}-\sqrt{5}}\)

\(=\dfrac{\left(2\sqrt{5}-6\right)\left(3+\sqrt{5}\right)}{4}-\dfrac{\left(2\sqrt{5}-2\sqrt{7}\right)\left(\sqrt{7}+\sqrt{5}\right)}{2}\)

\(=\dfrac{\left(\sqrt{5}-3\right)\left(3+\sqrt{5}\right)-\left(2\sqrt{5}-2\sqrt{7}\right)\left(\sqrt{7}+\sqrt{5}\right)}{2}\)

\(=\dfrac{5-9-2\left(5-7\right)}{2}\)

\(=\dfrac{-4-2\cdot\left(-2\right)}{2}\)

\(=0\)

Bài 2:

a: Thay x=-2 và y=-1 vào (d), ta được:

-2(m+1)+m+2=-1

=>-2m-2+m+2=-1

=>-m=-1

=>m=1

b: (d): y=2x+3

Tọa độ A là:

y=0 và 2x+3=0

=>x=-3/2 và y=0

=>OA=1,5

Tọa độ B là:

x=0 và y=2*0+3=3

=>OB=3

\(AB=\sqrt{1.5^2+3^2}=1.5\sqrt{5}\)

=>\(C=1.5+3+1.5\sqrt{5}=1.5\sqrt{5}+4.5\)

\(S=\dfrac{1}{2}\cdot OA\cdot OB=2.25\)
