\(D=\sqrt{13-\sqrt{160}}-\sqrt{53+4\sqrt{90}}=\sqrt{13-4\sqrt{10}}-\sqrt{53+12\sqrt{10}}\)
\(=\sqrt{8-2.2\sqrt{2}\sqrt{5}+5}-\sqrt{\text{coi lại đề}}\)
Rút gọn:
B=\(\sqrt{13-\sqrt{160}}-\sqrt{53+4\sqrt{90}}\)
Rút Gọn \(A=\sqrt{12-\sqrt{160}}-\sqrt{53+4\sqrt{90}}\)
\(\sqrt{13-\sqrt{160}}-\sqrt{53+4\sqrt{90}}\)
Tính
