Tính \(D=\left(13-4\sqrt{3}\right).\left(7+4\sqrt{3}\right)-8\sqrt{20+2\sqrt{43+24\sqrt{3}}}\)
B=\(\left(13-4\sqrt{3}\right)\left(7+4\sqrt{3}\right)-8\sqrt{20}+2\sqrt{43}+24\sqrt{3}\)
\(B=\left(13-4\sqrt{3}\right)\left(7+4\sqrt{3}\right)-8\sqrt{20+2\sqrt{43+24\sqrt{3}}}\)
Thu gọn biểu thức
\(A=\left(13-4\sqrt{3}\right)\left(7+4\sqrt{3}\right)-8\sqrt{20+2\sqrt{43+24\sqrt{3}}}\)
